hey people from around the world how are you my name is Rodrigo and this is
0:38
you my name is Rodrigo and this is
0:38
you my name is Rodrigo and this is Dabber in

Dabber in
0:39
Dabber in action today we're going to have a
0:42
action today we're going to have a
0:42
action today we're going to have a learning checkpoint after five
0:45
learning checkpoint after five
0:45
learning checkpoint after five sessions
0:47
sessions
0:47
sessions so let's get started okay
0:52
so let's get started okay
0:52
so let's get started okay so let's go through the materials right
0:56
so let's go through the materials right
0:56
so let's go through the materials right away Dapper this is a fantastic
0:59
away Dapper this is a fantastic
0:59
away Dapper this is a fantastic technology for creating distributed
1:01
technology for creating distributed
1:01
technology for creating distributed applications such as
1:03
applications such as
1:03
applications such as microservices
1:05
microservices
1:05
microservices and in the Dapper doio website you can
1:08
and in the Dapper doio website you can
1:08
and in the Dapper doio website you can find everything related to this
1:10
find everything related to this
1:10
find everything related to this fantastic technology it's part of the
1:12
fantastic technology it's part of the
1:12
fantastic technology it's part of the cloud native Computing Foundation it was
1:15
cloud native Computing Foundation it was
1:15
cloud native Computing Foundation it was originally created by Microsoft but
1:17
originally created by Microsoft but
1:18
originally created by Microsoft but nowadays is part of this
1:20
nowadays is part of this
1:20
nowadays is part of this cncf um so uh it allows you to create
1:26
cncf um so uh it allows you to create
1:26
cncf um so uh it allows you to create consistent and portable distributed
1:27
consistent and portable distributed
1:27
consistent and portable distributed applications it's sensible
1:30
applications it's sensible
1:30
applications it's sensible it's fantastic it's
1:32
it's fantastic it's
1:33
it's fantastic it's glorious and nowadays we're about to
1:36
glorious and nowadays we're about to
1:36
glorious and nowadays we're about to have Dapper 1.15 I guess sooner or
1:42
have Dapper 1.15 I guess sooner or
1:42
have Dapper 1.15 I guess sooner or later
1:44
later
1:44
later and actually let's go right here because
1:49
and actually let's go right here because
1:49
and actually let's go right here because I want to talk about the environment
1:52
I want to talk about the environment
1:52
I want to talk about the environment remember that you need to install Dapper
1:55
remember that you need to install Dapper
1:55
remember that you need to install Dapper right you need to download the Dapper
1:58
right you need to download the Dapper
1:58
right you need to download the Dapper CLI
2:00
CLI
2:00
CLI and then you have to initialize Dapper
2:04
and then you have to initialize Dapper
2:04
and then you have to initialize Dapper so let's go ahead
2:07
so let's go ahead
2:07
so let's go ahead and here in the terminal you have to
2:11
and here in the terminal you have to
2:11
and here in the terminal you have to type something like Dapper in it after
2:14
type something like Dapper in it after
2:14
type something like Dapper in it after you install the CLR of course I have the
2:17
you install the CLR of course I have the
2:17
you install the CLR of course I have the C
2:18
C
2:18
C CLI uh not CLR CLI right here um you can
2:23
CLI uh not CLR CLI right here um you can
2:23
CLI uh not CLR CLI right here um you can see that I installed previously
2:26
see that I installed previously
2:26
see that I installed previously Dapper and I have this version which
2:30
Dapper and I have this version which
2:30
Dapper and I have this version which is version
2:32
is version
2:33
is version 1.14 I think and this is actually the
2:37
1.14 I think and this is actually the
2:37
1.14 I think and this is actually the version that I'm running
2:40
version that I'm running
2:40
version that I'm running okay
2:43
okay
2:43
okay so of course you can go ahead and
2:46
so of course you can go ahead and
2:46
so of course you can go ahead and navigate to Dapper
2:48
navigate to Dapper
2:48
navigate to Dapper doio and then you can click here in the
2:53
doio and then you can click here in the
2:53
doio and then you can click here in the get started button and then click on
2:56
get started button and then click on
2:56
get started button and then click on install the dopper
2:58
install the dopper
2:58
install the dopper CLI and if you you're using Windows like
3:01
CLI and if you you're using Windows like
3:01
CLI and if you you're using Windows like I like I do then you need to run this
3:05
I like I do then you need to run this
3:05
I like I do then you need to run this particular script for installing Dapper
3:09
particular script for installing Dapper
3:09
particular script for installing Dapper okay so I I already did this that's why
3:13
okay so I I already did this that's why
3:13
okay so I I already did this that's why I have the Dapper CLI then you have to
3:15
I have the Dapper CLI then you have to
3:15
I have the Dapper CLI then you have to initialize
3:16
initialize
3:16
initialize Dapper and here is where the magic
3:20
Dapper and here is where the magic
3:20
Dapper and here is where the magic happens
3:21
happens
3:22
happens because um this is the place or this is
3:25
because um this is the place or this is
3:25
because um this is the place or this is the command that is going to download
3:27
the command that is going to download
3:27
the command that is going to download all the different components for Dapper
3:31
all the different components for Dapper
3:31
all the different components for Dapper and you need to have installed Docker
3:33
and you need to have installed Docker
3:33
and you need to have installed Docker well actually you don't need to but it's
3:36
well actually you don't need to but it's
3:36
well actually you don't need to but it's actually
3:37
actually
3:37
actually recommended and of course there's an
3:40
recommended and of course there's an
3:40
recommended and of course there's an Dapper option for initializing Dapper
3:43
Dapper option for initializing Dapper
3:43
Dapper option for initializing Dapper without uh using
3:46
without uh using
3:46
without uh using Docker and as you can see here I already
3:50
Docker and as you can see here I already
3:50
Docker and as you can see here I already initialized upper so those Docker
3:52
initialized upper so those Docker
3:52
initialized upper so those Docker containers are running on my machine
3:54
containers are running on my machine
3:54
containers are running on my machine right
3:55
right
3:55
right now okay so everything so far so good
3:59
now okay so everything so far so good
3:59
now okay so everything so far so good and
4:00
and
4:00
and this is actually what you need to do to
4:02
this is actually what you need to do to
4:02
this is actually what you need to do to get started with Dapper
4:05
get started with Dapper
4:05
get started with Dapper okay so I'm using doet 9 and I'm using
4:10
okay so I'm using doet 9 and I'm using
4:10
okay so I'm using doet 9 and I'm using Docker desktop I can show you that here
4:14
Docker desktop I can show you that here
4:14
Docker desktop I can show you that here in this screen you can see that Docker
4:17
in this screen you can see that Docker
4:17
in this screen you can see that Docker desktop is running right and I'm using
4:20
desktop is running right and I'm using
4:20
desktop is running right and I'm using visual studio uh 2022 and I'm also using
4:23
visual studio uh 2022 and I'm also using
4:23
visual studio uh 2022 and I'm also using visual studio code there's a Dapper
4:25
visual studio code there's a Dapper
4:25
visual studio code there's a Dapper extension for visual studio code for
4:28
extension for visual studio code for
4:28
extension for visual studio code for debugging purposes I think that's
4:31
debugging purposes I think that's
4:31
debugging purposes I think that's perfect and there's also um an extension
4:35
perfect and there's also um an extension
4:35
perfect and there's also um an extension for visual studio
4:37
for visual studio
4:37
for visual studio 2022 and or you can always use any other
4:40
2022 and or you can always use any other
4:40
2022 and or you can always use any other kind of editor but actually this is the
4:43
kind of editor but actually this is the
4:43
kind of editor but actually this is the environment that we have in this Dapper
4:46
environment that we have in this Dapper
4:46
environment that we have in this Dapper in action Series so you initialize
4:49
in action Series so you initialize
4:49
in action Series so you initialize Dapper and then Dapper is going to be
4:52
Dapper and then Dapper is going to be
4:52
Dapper and then Dapper is going to be installed in this
4:55
installed in this
4:55
installed in this particular path let's go to this path in
4:59
particular path let's go to this path in
4:59
particular path let's go to this path in this case I'm using this other machine
5:00
this case I'm using this other machine
5:00
this case I'm using this other machine as you can see this is not my regular
5:03
as you can see this is not my regular
5:03
as you can see this is not my regular machine and here you can find the do
5:06
machine and here you can find the do
5:06
machine and here you can find the do dopper folder in inside the folder
5:09
dopper folder in inside the folder
5:09
dopper folder in inside the folder you're going to find the bin folder that
5:13
you're going to find the bin folder that
5:13
you're going to find the bin folder that has all the binaries related to Dapper
5:16
has all the binaries related to Dapper
5:16
has all the binaries related to Dapper and also you can find this components
5:20
and also you can find this components
5:20
and also you can find this components folder that has the default components
5:24
folder that has the default components
5:24
folder that has the default components for pops up in the State Management
5:27
for pops up in the State Management
5:27
for pops up in the State Management building
5:28
building
5:28
building blocks and here you can also find this
5:32
blocks and here you can also find this
5:32
blocks and here you can also find this configuration where you can set some
5:34
configuration where you can set some
5:34
configuration where you can set some other things some um cross cutting
5:38
other things some um cross cutting
5:38
other things some um cross cutting concerns about
5:40
concerns about
5:40
concerns about Dapper so that's perfect so you
5:43
Dapper so that's perfect so you
5:43
Dapper so that's perfect so you initialize Dapper this is the command
5:45
initialize Dapper this is the command
5:45
initialize Dapper this is the command that you use if you don't have
5:48
that you use if you don't have
5:48
that you use if you don't have Docker because let's be honest sometimes
5:52
Docker because let's be honest sometimes
5:52
Docker because let's be honest sometimes you're not allowed to use Docker in your
5:55
you're not allowed to use Docker in your
5:55
you're not allowed to use Docker in your machine or I don't know good evening my
5:58
machine or I don't know good evening my
5:58
machine or I don't know good evening my friend amand
6:01
and so everything is running perfectly
6:05
and so everything is running perfectly
6:05
and so everything is running perfectly and so far so good if you want to
6:07
and so far so good if you want to
6:07
and so far so good if you want to uninstall dopper then you can execute
6:10
uninstall dopper then you can execute
6:10
uninstall dopper then you can execute dopper uninstall and then this is going
6:13
dopper uninstall and then this is going
6:14
dopper uninstall and then this is going to uninstall the binaries and if you
6:16
to uninstall the binaries and if you
6:16
to uninstall the binaries and if you want also to remove the containers then
6:18
want also to remove the containers then
6:18
want also to remove the containers then you can pass that all flag and that's it
6:22
you can pass that all flag and that's it
6:22
you can pass that all flag and that's it so configuration is inside that config
6:26
so configuration is inside that config

6:47
we've been using that file a couple of
6:47
we've been using that file a couple of times in this series so you can see here
6:49
times in this series so you can see here
6:49
times in this series so you can see here on the screen those tracing and metrics
6:53
on the screen those tracing and metrics
6:53
on the screen those tracing and metrics and logging those elements are the uh
6:58
and logging those elements are the uh

7:09
Abu hi there my
7:09
Abu hi there my friend so the dopper CLI is actually the
7:14
friend so the dopper CLI is actually the
7:14
friend so the dopper CLI is actually the tool that you need to master in order to
7:17
tool that you need to master in order to
7:17
tool that you need to master in order to create great and fabulous Dapper um
7:22
create great and fabulous Dapper um
7:23
create great and fabulous Dapper um Solutions and there are some commands
7:26
Solutions and there are some commands
7:26
Solutions and there are some commands related to the selfhosted mode that I've
7:28
related to the selfhosted mode that I've
7:28
related to the selfhosted mode that I've been using in this series and there are
7:31
been using in this series and there are
7:31
been using in this series and there are some other commands for
7:33
some other commands for
7:33
some other commands for kubernetes uh because at the end of the
7:35
kubernetes uh because at the end of the
7:35
kubernetes uh because at the end of the day Dapper can run as a tight car
7:37
day Dapper can run as a tight car
7:37
day Dapper can run as a tight car container inside kubernetes and we're
7:39
container inside kubernetes and we're
7:39
container inside kubernetes and we're going to see that in a future
7:43
going to see that in a future
7:43
going to see that in a future chapter so dopper version for showing
7:46
chapter so dopper version for showing
7:46
chapter so dopper version for showing the dopper runtime and CLI
7:48
the dopper runtime and CLI
7:49
the dopper runtime and CLI versions and dopper help dopper list for
7:52
versions and dopper help dopper list for
7:52
versions and dopper help dopper list for showing all the instances that are
7:53
showing all the instances that are
7:53
showing all the instances that are running in thater dashboard we seen
7:56
running in thater dashboard we seen
7:56
running in thater dashboard we seen those uh commands already in this series
8:00
those uh commands already in this series
8:01
those uh commands already in this series so yes Dapper is fantastic but of course
8:04
so yes Dapper is fantastic but of course
8:04
so yes Dapper is fantastic but of course it's not a programming language it's a
8:07
it's not a programming language it's a
8:07
it's not a programming language it's a framework right for oh actually it's a
8:11
framework right for oh actually it's a
8:11
framework right for oh actually it's a yes it's a framework it's a a hosting
8:13
yes it's a framework it's a a hosting
8:13
yes it's a framework it's a a hosting environment and there is a a series of
8:16
environment and there is a a series of
8:16
environment and there is a a series of different
8:17
different
8:17
different components um so you need to run the
8:20
components um so you need to run the
8:20
components um so you need to run the side car somehow as I've mentioned
8:22
side car somehow as I've mentioned
8:22
side car somehow as I've mentioned before you can run Dapper as a sidecar
8:25
before you can run Dapper as a sidecar
8:26
before you can run Dapper as a sidecar container inside
8:28
container inside
8:28
container inside kubernetes uh but of course if you're
8:32
kubernetes uh but of course if you're
8:32
kubernetes uh but of course if you're building a dopper application some of
8:34
building a dopper application some of
8:34
building a dopper application some of sometimes you need to run the side card
8:36
sometimes you need to run the side card
8:36
sometimes you need to run the side card by itself right this is the selfhosted
8:39
by itself right this is the selfhosted
8:39
by itself right this is the selfhosted mode that we use and we've been using in
8:42
mode that we use and we've been using in
8:42
mode that we use and we've been using in this series so you need to specify the
8:46
this series so you need to specify the
8:46
this series so you need to specify the application
8:48
application
8:48
application identifier say service one service B
8:51
identifier say service one service B
8:51
identifier say service one service B service C and then the dopper HTTP port
8:56
service C and then the dopper HTTP port
8:56
service C and then the dopper HTTP port in other words the port number where the
9:00
in other words the port number where the
9:00
in other words the port number where the Dapper side card is going to expose the
9:03
Dapper side card is going to expose the
9:03
Dapper side card is going to expose the API for HTT for the HTTP
9:08
API for HTT for the HTTP
9:08
API for HTT for the HTTP protocol and there's a grpc port for
9:12
protocol and there's a grpc port for
9:12
protocol and there's a grpc port for exposing the API through that particular
9:16
exposing the API through that particular
9:16
exposing the API through that particular technology so in other words we can we
9:19
technology so in other words we can we
9:19
technology so in other words we can we can get access to Dapper by using HTTP
9:23
can get access to Dapper by using HTTP
9:23
can get access to Dapper by using HTTP or the drpc
9:25
or the drpc
9:25
or the drpc Technologies and a port this is the port
9:28
Technologies and a port this is the port
9:28
Technologies and a port this is the port number
9:29
number
9:29
number where your application is listening
9:32
where your application is listening
9:32
where your application is listening on and then you need to specify Double
9:36
on and then you need to specify Double
9:36
on and then you need to specify Double Dash for your specific application
9:40
Dash for your specific application
9:40
Dash for your specific application instructions for instance if you're
9:42
instructions for instance if you're
9:42
instructions for instance if you're running net then this is a place where
9:45
running net then this is a place where
9:45
running net then this is a place where you pass net Ron and all the flags that
9:49
you pass net Ron and all the flags that
9:49
you pass net Ron and all the flags that your application needs such as URLs and
9:52
your application needs such as URLs and
9:52
your application needs such as URLs and so on so there's an example here on the
9:55
so on so there's an example here on the
9:55
so on so there's an example here on the screen that I've been using you know
9:59
screen that I've been using you know
9:59
screen that I've been using you know most of the time in this series
10:01
most of the time in this series
10:01
most of the time in this series okay perfect so we can also run multiple
10:05
okay perfect so we can also run multiple
10:05
okay perfect so we can also run multiple apps at the same time this is similar to
10:08
apps at the same time this is similar to
10:08
apps at the same time this is similar to a Docker compos file we need to create
10:11
a Docker compos file we need to create
10:11
a Docker compos file we need to create this Dapper doj file inside the
10:15
this Dapper doj file inside the
10:15
this Dapper doj file inside the directory and then you can specify all
10:18
directory and then you can specify all
10:18
directory and then you can specify all the different applications that you want
10:19
the different applications that you want
10:19
the different applications that you want to run at the same time this is Magic
10:23
to run at the same time this is Magic
10:23
to run at the same time this is Magic right this is this is great such as dock
10:26
right this is this is great such as dock
10:26
right this is this is great such as dock compose right instead of running each
10:29
compose right instead of running each
10:29
compose right instead of running each application
10:31
application
10:31
application separately so this is the schema for
10:33
separately so this is the schema for
10:33
separately so this is the schema for that particular dopper doj
10:37
that particular dopper doj
10:37
that particular dopper doj file uh and by the way the name can
10:41
file uh and by the way the name can
10:41
file uh and by the way the name can be just any other name and um but
10:46
be just any other name and um but
10:46
be just any other name and um but actually the default values uh doer.
10:48
actually the default values uh doer.
10:48
actually the default values uh doer. jaml so this is the place you can see
10:51
jaml so this is the place you can see
10:51
jaml so this is the place you can see here on the screen that this J file is
10:54
here on the screen that this J file is
10:54
here on the screen that this J file is specifying two applications web app and
10:57

use an official
11:55
use an official SDK that's why our friends from dapper
11:59
SDK that's why our friends from dapper
11:59
SDK that's why our friends from dapper they create those sdks so let's use the
12:03
they create those sdks so let's use the
12:03
they create those sdks so let's use the those sdks in our
12:05
those sdks in our

applications that are you know that they
13:52
applications that are you know that they have different services or
13:54
have different services or
13:54
have different services or microservices so you need to know when
13:58
microservices so you need to know when
13:58
microservices so you need to know when something happen
14:00
something happen
14:00
something happen in this other service
14:03
in this other service
14:03
in this other service right so you need to react somehow when

right so you need to react somehow when
14:06
right so you need to react somehow when some event happened in service a you
14:11
some event happened in service a you
14:11
some event happened in service a you want service B and service C and service
14:14
want service B and service C and service

so this particular diagram shows the
14:35
so this particular diagram shows the pops up component in action you have a
14:38
pops up component in action you have a

event right and if you want to use the API directly which I do not recommend as
14:56
API directly which I do not recommend as

API directly which I do not recommend as I've mentioned before uh um you can use
15:00
I've mentioned before uh um you can use

consultations when a new patient is
21:56
consultations when a new patient is created why because those two
22:00
created why because those two
22:00
created why because those two microservices they have their own
22:03
microservices they have their own
22:03
microservices they have their own database I think that's fine for most of
22:07
database I think that's fine for most of
22:07
database I think that's fine for most of the time when you're using
22:09
the time when you're using
22:09
the time when you're using microservices but what
22:11
microservices but what
22:11
microservices but what happens let's think about this um let's
22:16
happens let's think about this um let's
22:16
happens let's think about this um let's think about a
22:21
consultation oh my God I'm sorry about
22:25
consultation oh my God I'm sorry about
22:25
consultation oh my God I'm sorry about that
22:27
that
22:27
that anyway so when a consultation happens
22:30
anyway so when a consultation happens
22:30
anyway so when a consultation happens between a patient and a doctor as you
22:32
between a patient and a doctor as you
22:32
between a patient and a doctor as you can see here I'm receiving this as the
22:36
can see here I'm receiving this as the
22:36
can see here I'm receiving this as the payload right patient and
22:40
payload right patient and
22:40
payload right patient and doctor so I know the ID of the
22:44
doctor so I know the ID of the
22:44
doctor so I know the ID of the patient
22:47
patient
22:47
patient right however I don't know the name of
22:51
right however I don't know the name of
22:52
right however I don't know the name of the patient since the source of Truth
22:57
the patient since the source of Truth
22:57
the patient since the source of Truth for patients
22:59
for patients
22:59
for patients must be patient
23:01
must be patient
23:01
must be patient API in other words this other
23:04
API in other words this other
23:04
API in other words this other microservice right so I need a way
23:08
microservice right so I need a way
23:08
microservice right so I need a way between microservices to store some kind
23:10
between microservices to store some kind
23:11
between microservices to store some kind of cash and that's actually what I'm
23:13
of cash and that's actually what I'm
23:13
of cash and that's actually what I'm going to do
23:14
going to do
23:14
going to do here
23:16
here

here and I have this code that I've been

with so you can see here on the patient controller
23:30
controller

23:33
when I create a patient right let's say
23:33
when I create a patient right let's say Steven
23:34
Steven
23:34
Steven Simon I create this patient named Steven
23:37
Simon I create this patient named Steven
23:37
Simon I create this patient named Steven Simon and then I want to publish the

23:52
payload this is the only thing that you
23:52
payload this is the only thing that you need to do in order to use the pops up
23:55

controller I have this public method that is decorated with the topic
24:12
that is decorated with the topic
24:12
that is decorated with the topic attribute again I'm using the same pops

this is it this is actually it there's nothing else you can do or you should do
24:35
nothing else you can do or you should do
24:35
nothing else you can do or you should do in order to receive that patient
24:38
in order to receive that patient
24:39
in order to receive that patient object can you see what's happening here
24:42
object can you see what's happening here
24:42
object can you see what's happening here so patient is going to send a
24:44
so patient is going to send a

so patient is going to send a synchronously that event and this guy is
24:47
synchronously that event and this guy is
24:47
synchronously that event and this guy is you know waiting for messages in the

pops up
24:52
pops up component and when there when there's a

24:57
new message it's going to grab the

new message it's going to grab the object it's going to grab the message
24:59
object it's going to grab the message
24:59
object it's going to grab the message right and it's going to
25:01
right and it's going to

right and it's going to deserialize that message into this uh
25:05
deserialize that message into this uh
25:05
deserialize that message into this uh strongly type object and I'm going to
25:08
strongly type object and I'm going to

strongly type object and I'm going to use that for inserting the patient in
25:12
use that for inserting the patient in
