On March 17, join us for the next episode of Dapr in Action a weekly live show at 11:00 AM (EST) focused on What is the Jobs.
In this episode, you will understand what Jobs is, what are some of its concrete component implementations and how you can use it in your own applications.
ABSTRACT
A new weekly series about creating robust distributed applications and microservices using Dapr (Distributed Application Runtime).
Developers and software architects who are building distributed applications and/or microservices and they want to understand how Dapr can make their lives easier. I will use .NET and C#, but will try to use other languages as well (for example, Python).

this is your host Rodrigo and this is another episode of the dber in action
0:39
another episode of the dber in action
0:39
another episode of the dber in action series and have you ever wondered how to
0:42
series and have you ever wondered how to
0:42
series and have you ever wondered how to run jobs with
0:45
run jobs with
0:45
run jobs with zapper I've got you covered and we're
0:49
zapper I've got you covered and we're
0:49
zapper I've got you covered and we're GNA see that today we're gonna see the
0:51
GNA see that today we're gonna see the
0:51
GNA see that today we're gonna see the jobs API and I'm going to show you how
0:55
jobs API and I'm going to show you how
0:55
jobs API and I'm going to show you how easy it is to execute
0:58
easy it is to execute
0:58
easy it is to execute things in the future that's what jobs is
1:02
things in the future that's what jobs is
1:02
things in the future that's what jobs is all about right
1:05
all about right
1:05
all about right so um this is going to be great just let
1:09
so um this is going to be great just let
1:09
so um this is going to be great just let me see if this is connected yes this is
1:13
me see if this is connected yes this is
1:13
me see if this is connected yes this is connected and this is because I'm in my
1:18
connected and this is because I'm in my
1:18
connected and this is because I'm in my uh laptop this time I'm not in my
1:21
uh laptop this time I'm not in my
1:21
uh laptop this time I'm not in my desktop
1:22
desktop
1:22
desktop PC
1:24
PC
1:24
PC and so what are some of the scenarios
1:28
and so what are some of the scenarios
1:28
and so what are some of the scenarios that the jobs API
1:30
that the jobs API
1:30
that the jobs API solve uh just imagine if you want to
1:34
solve uh just imagine if you want to
1:34
solve uh just imagine if you want to make some
1:36
make some
1:36
make some backups daily or weekly or monthly that
1:40
backups daily or weekly or monthly that
1:40
backups daily or weekly or monthly that would be a great scenario for using the
1:42
would be a great scenario for using the
1:42
would be a great scenario for using the jobs API or maybe your boss or somebody
1:47
jobs API or maybe your boss or somebody
1:47
jobs API or maybe your boss or somebody one of your colleagues is asking you to
1:49
one of your colleagues is asking you to
1:49
one of your colleagues is asking you to create some
1:51
create some
1:51
create some reports um and you want to do that in a
1:55
reports um and you want to do that in a
1:55
reports um and you want to do that in a scheduled way so that's another example
1:59
scheduled way so that's another example
1:59
scheduled way so that's another example or maybe you want to run or execute some
2:01
or maybe you want to run or execute some
2:02
or maybe you want to run or execute some health checks in your application or
2:03
health checks in your application or
2:03
health checks in your application or your system that's another example right
2:07
your system that's another example right
2:08
your system that's another example right data synchronization across
2:10
data synchronization across
2:10
data synchronization across microservices or across
2:13
microservices or across
2:13
microservices or across applications or maybe you want to create
2:16
applications or maybe you want to create
2:16
applications or maybe you want to create some documents maybe you you want to
2:19
some documents maybe you you want to
2:19
some documents maybe you you want to process some kind of uh I don't know
2:22
process some kind of uh I don't know
2:22
process some kind of uh I don't know invoices or maybe you want to create
2:24
invoices or maybe you want to create
2:24
invoices or maybe you want to create some kind of um watermarks for your
2:28
some kind of um watermarks for your
2:28
some kind of um watermarks for your images or or I don't know it all depends
2:33
images or or I don't know it all depends
2:33
images or or I don't know it all depends right even you can even models uh I'm
2:37
right even you can even models uh I'm
2:37
right even you can even models uh I'm sorry train some models by using this um
2:41
sorry train some models by using this um
2:41
sorry train some models by using this um jobs

2:48
so um I'm going to show you that today
2:48
so um I'm going to show you that today and here are some notes that I want to
2:50
and here are some notes that I want to
2:50
and here are some notes that I want to talk about later
2:52
talk about later
2:52
talk about later today but let's Jump Right In the jobs
2:56
today but let's Jump Right In the jobs
2:56
today but let's Jump Right In the jobs API you get access to it by by using
3:00
API you get access to it by by using
3:00
API you get access to it by by using this dopper side carard right like any
3:04
this dopper side carard right like any
3:04
this dopper side carard right like any other building block in
3:06
other building block in
3:06
other building block in Dapper you need the side car and the
3:09
Dapper you need the side car and the
3:09
Dapper you need the side car and the side car is going to use the Dapper
3:14
side car is going to use the Dapper
3:14
side car is going to use the Dapper scheduler right so remember Dapper
3:16
scheduler right so remember Dapper
3:16
scheduler right so remember Dapper scheduler that's one of the services
3:19
scheduler that's one of the services
3:19
scheduler that's one of the services that is executed when we Dapper in it
3:22
that is executed when we Dapper in it
3:23
that is executed when we Dapper in it the local application I'm sorry the
3:26
the local application I'm sorry the
3:26
the local application I'm sorry the local system or your kubernetes cluster
3:30
local system or your kubernetes cluster
3:30
local system or your kubernetes cluster actually let me go to the terminal to
3:34
actually let me go to the terminal to
3:34
actually let me go to the terminal to show you the
3:37
show you the
3:37
show you the following so I'm gonna execute Docker PS
3:42
following so I'm gonna execute Docker PS
3:42
following so I'm gonna execute Docker PS right
3:44
right
3:44
right and here's the
3:46
and here's the
3:46
and here's the scheduler and this is running because of
3:49
scheduler and this is running because of
3:49
scheduler and this is running because of the fact that I initialized oper in this
3:52
the fact that I initialized oper in this

4:00
Dapper 15 I'm sorry 1.15
4:00
Dapper 15 I'm sorry 1.15 uh since that that's the latest version
4:02
uh since that that's the latest version
4:02
uh since that that's the latest version of the of the platform right so you have
4:08
of the of the platform right so you have
4:08
of the of the platform right so you have to have the scheduler the scheduler has
4:12
to have the scheduler the scheduler has
4:12
to have the scheduler the scheduler has has to run right has to be executing in
4:15
has to run right has to be executing in
4:15
has to run right has to be executing in order to uh schedule some jobs to
4:20
order to uh schedule some jobs to
4:20
order to uh schedule some jobs to it and then you use the D side card in
4:24
it and then you use the D side card in
4:24
it and then you use the D side card in your application and you send some
4:27
your application and you send some
4:27
your application and you send some metadata and then the scheduler is going
4:31
metadata and then the scheduler is going
4:31
metadata and then the scheduler is going to be
4:32
to be
4:32
to be sure that an endpoint that you specify
4:36
sure that an endpoint that you specify
4:36
sure that an endpoint that you specify is going to be called back when the
4:40
is going to be called back when the
4:40
is going to be called back when the scheduling kicks
4:42
scheduling kicks
4:42
scheduling kicks in okay so let's do this
4:47
in okay so let's do this
4:47
in okay so let's do this today so let's go here to the daer

5:53
so that's one thing let's do the
5:53
so that's one thing let's do the build everything is working
5:56
build everything is working
5:56
build everything is working perfectly and finally let's add some

that's it actually that is it so jobs. sln
6:17
it actually that is it so jobs. sln
6:17
it actually that is it so jobs. sln since I want to use Microsoft Visual

6:24
2022 to create some
6:24
2022 to create some code so remember the jobs API
6:30
code so remember the jobs API
6:30
code so remember the jobs API in other words the jobs SDK for the jobs
6:35
in other words the jobs SDK for the jobs
6:35
in other words the jobs SDK for the jobs API

6:49
package now you need to add the Dapper
6:49
package now you need to add the Dapper job support to your
6:52
job support to your
6:52
job support to your application so I'm going to do that here
6:55

Dapper Dapper jobs and I don't have
7:08
Dapper Dapper jobs and I don't have Microsoft copil enabled so using Dapper
7:13
Microsoft copil enabled so using Dapper

Microsoft copil enabled so using Dapper using Dapper do um jobs and then using
7:18
using Dapper do um jobs and then using
7:18
using Dapper do um jobs and then using Dapper do jobs.
7:20
Dapper do jobs.
7:20
Dapper do jobs. extensions since I don't remember the

name it set it's going to be HTTP post just a regular endpoint and now I can go
8:43
just a regular endpoint and now I can go
8:43
just a regular endpoint and now I can go ahead
8:45
ahead
8:45
ahead and execute scheduled job
8:49
and execute scheduled job
8:49
and execute scheduled job acing right and you can set the job name
8:53
acing right and you can set the job name
8:53
acing right and you can set the job name as you can see here on the screen and
8:56
as you can see here on the screen and
8:56
as you can see here on the screen and then the scheduling configuration
9:00
then the scheduling configuration
9:00
then the scheduling configuration so for instance let's name this my job
9:04
so for instance let's name this my job
9:04
so for instance let's name this my job right it could be a good you can specify
9:09
right it could be a good you can specify
9:09
right it could be a good you can specify your own naming pattern if you like you
9:14
your own naming pattern if you like you
9:14
your own naming pattern if you like you can actually send that here as part of
9:17
can actually send that here as part of
9:17
can actually send that here as part of the payload that this endpoint is
9:20
the payload that this endpoint is
9:20
the payload that this endpoint is receiving however I'm going to set the
9:23
receiving however I'm going to set the
9:23
receiving however I'm going to set the name as my job okay cool now doer job
9:28
name as my job okay cool now doer job
9:28
name as my job okay cool now doer job schedule
9:30
schedule
9:30
schedule Dapper job schedule has those
9:35
Dapper job schedule has those
9:35
Dapper job schedule has those properties and it actually has
9:39
properties and it actually has
9:39
properties and it actually has some uh static methods for creating the
9:43
some uh static methods for creating the
9:43
some uh static methods for creating the scheduling uh
9:45
scheduling uh
9:45
scheduling uh configuration for example if you want to
9:49
configuration for example if you want to
9:49
configuration for example if you want to execute the
9:51
execute the
9:51
execute the job in a
9:54
job in a
9:54
job in a particular uh
9:55
particular uh
9:55
particular uh moment let's say that I want to execute
9:58
moment let's say that I want to execute
9:58
moment let's say that I want to execute the f
10:00
the f
10:00
the f job in one minute from now so from
10:06
job in one minute from now so from
10:06
job in one minute from now so from minutes right
10:08
minutes right
10:08
minutes right from minutes then one that could be one
10:13
from minutes then one that could be one
10:13
from minutes then one that could be one option or maybe you want to use those
10:17
option or maybe you want to use those
10:17
option or maybe you want to use those other properties maybe you want to use
10:20
other properties maybe you want to use
10:20
other properties maybe you want to use hourly for executing the job in an
10:24
hourly for executing the job in an
10:24
hourly for executing the job in an hourly fashion or weekly or daily and so
10:27
hourly fashion or weekly or daily and so
10:27
hourly fashion or weekly or daily and so on or daily right right midnight monthly
10:32
on or daily right right midnight monthly
10:32
on or daily right right midnight monthly so as you can see those are scheduling
10:34
so as you can see those are scheduling
10:34
so as you can see those are scheduling configurations that are pretty pretty
10:37
configurations that are pretty pretty
10:37
configurations that are pretty pretty helpful when you want to set the
10:41
helpful when you want to set the
10:41
helpful when you want to set the scheduling right in this case I want to
10:43
scheduling right in this case I want to
10:43
scheduling right in this case I want to use from duration since I want to do
10:48
use from duration since I want to do
10:48
use from duration since I want to do things quite easy
10:51
things quite easy
10:51
things quite easy today so I'm going to schedule the job
10:55
today so I'm going to schedule the job
10:55
today so I'm going to schedule the job in the following one minute and then
10:59
in the following one minute and then
10:59
in the following one minute and then let's see what's going on
11:01
let's see what's going on
11:02
let's see what's going on here so this is from duration that's
11:05
here so this is from duration that's
11:05
here so this is from duration that's perfect that's the daer job schedule
11:07
perfect that's the daer job schedule
11:07
perfect that's the daer job schedule object and then you need to specify that
11:10
object and then you need to specify that
11:10
object and then you need to specify that read only memory of
11:13
read only memory of
11:13
read only memory of bite in other words you need to S you
11:17
bite in other words you need to S you
11:17
bite in other words you need to S you you need to serialize your data your
11:20
you need to serialize your data your
11:20
you need to serialize your data your payload that you want to send to the
11:22
payload that you want to send to the
11:22
payload that you want to send to the scheduler
11:25
scheduler
11:25
scheduler right speaking of which let's create a
11:28
right speaking of which let's create a
11:28
right speaking of which let's create a new record record my job or something
11:32
new record record my job or something
11:32
new record record my job or something let's name it
11:34
let's name it
11:34
let's name it name my job that's the name and I want
11:37
name my job that's the name and I want
11:37
name my job that's the name and I want to have this property which is
11:39
to have this property which is
11:39
to have this property which is name and again this is this depends on
11:44
name and again this is this depends on
11:44
name and again this is this depends on your requirements right I'm just
11:46
your requirements right I'm just
11:46
your requirements right I'm just creating this record it could be a class
11:49
creating this record it could be a class
11:49
creating this record it could be a class it could be any other kind of a
11:51
it could be any other kind of a
11:51
it could be any other kind of a structure uh as far as it can be
11:55
structure uh as far as it can be
11:55
structure uh as far as it can be serialized
11:57
serialized
11:57
serialized okay um
11:59
okay um
11:59
okay um perfect now let's serialize the thing so
12:04
perfect now let's serialize the thing so
12:04
perfect now let's serialize the thing so Json serializer that comes from system.
12:08
Json serializer that comes from system.
12:08

right and we need some way to tell Dapper hey this is the Callback this is
14:56
Dapper hey this is the Callback this is
14:56
Dapper hey this is the Callback this is the end point that I want you to execute
15:01
the end point that I want you to execute
15:01
the end point that I want you to execute when the schedule comes right when the
15:04
when the schedule comes right when the

when the schedule comes right when the schedule job kicks
15:07
schedule job kicks
15:07
schedule job kicks in so I'm going to do that here in the

job Handler and as you can see here you need
15:20
Handler and as you can see here you need
15:20
Handler and as you can see here you need to pass this
15:23
delegate right and then you can also
15:27
delegate right and then you can also
15:27
delegate right and then you can also optionally pass the
15:29
optionally pass the
15:29
optionally pass the the time span for the

sending emails or again it
16:49
sending emails or again it depends okay so far so
16:52
depends okay so far so
16:52
depends okay so far so good um so first you need to specify
16:57
good um so first you need to specify
16:57
good um so first you need to specify this you need to config your your
16:59
this you need to config your your
16:59
this you need to config your your asp.net core application if you happen
17:01
asp.net core application if you happen
17:01
asp.net core application if you happen to be an asp.net core
17:04
to be an asp.net core
17:04
to be an asp.net core developer you need to execute this so
17:07
developer you need to execute this so
17:07
developer you need to execute this so you can use the dopper jobs client
17:10
you can use the dopper jobs client
17:10
you can use the dopper jobs client object in your
17:12
object in your
17:12
object in your controllers like this I'm injecting the
17:15
controllers like this I'm injecting the
17:15
controllers like this I'm injecting the doer jobs client and then I'm creating
17:18
doer jobs client and then I'm creating
17:18
doer jobs client and then I'm creating the object that represents the job and
17:21
the object that represents the job and
17:21
the object that represents the job and then I'm setting the scheduling
17:24
then I'm setting the scheduling
17:24
then I'm setting the scheduling configuration then I'm sending the job
17:27
configuration then I'm sending the job
17:27
configuration then I'm sending the job to the scheduler
17:29
to the scheduler
17:29
to the scheduler here in line
17:32
here in line
17:32
here in line 18 uh you need to specify a name and
17:35
18 uh you need to specify a name and
17:35
18 uh you need to specify a name and that is it that is actually
17:39
that is it that is actually
17:39
that is it that is actually it okay so far so good let's do the
17:47
following let's execute the dopper side
17:50
following let's execute the dopper side
17:50
following let's execute the dopper side car so dopper
17:53
car so dopper
17:53
car so dopper run and app ID let's name IT jobs and
17:58
run and app ID let's name IT jobs and
17:58
run and app ID let's name IT jobs and then topper HTTP Port it's going to be
18:03
then topper HTTP Port it's going to be
18:03
then topper HTTP Port it's going to be 5500 and then app
18:05
5500 and then app
18:05
5500 and then app Port let's say 55 0 this is 55,000 right
18:12
Port let's say 55 0 this is 55,000 right
18:12
Port let's say 55 0 this is 55,000 right and then
18:14
5500 and
18:17
5500 and
18:17
5500 and net run and URLs HTTP since I want to be
18:23
net run and URLs HTTP since I want to be
18:23
net run and URLs HTTP since I want to be sure that this application is running in
18:25
sure that this application is running in
18:25
sure that this application is running in this
18:26
this
18:26
this port make sense
18:30
port make sense
18:30
port make sense in other
18:31
in other
18:31
in other words I'm just executing the topper side
18:34
words I'm just executing the topper side
18:34
words I'm just executing the topper side car alongside my application just like
18:37
car alongside my application just like
18:37
car alongside my application just like any other regular topper application in
18:40
any other regular topper application in
18:40
any other regular topper application in the
18:41
the
18:41
the past
18:42
past
18:42
past okay so let's execute this
18:50
and this is
18:52
and this is
18:52
and this is running it's running
18:56
running it's running
18:56
running it's running right so if telling me hey hi hi hi hi
19:00
right so if telling me hey hi hi hi hi
19:00
right so if telling me hey hi hi hi hi because I made some
19:03
because I made some
19:03
because I made some uh uh previous
19:06
uh uh previous
19:06
uh uh previous tests uh let's go here and let's change
19:10
tests uh let's go here and let's change
19:10
tests uh let's go here and let's change the name let's change this stram
19:14
the name let's change this stram
19:15
the name let's change this stram hello this is the job
19:21
executing make sense
19:24
executing make sense
19:24
executing make sense since I was running the same application
19:28
since I was running the same application
19:28
since I was running the same application before
19:29
before
19:29
before so let's ex execute this
19:34
again so okay hello this is the job
19:37
again so okay hello this is the job
19:37
again so okay hello this is the job executing can you see
19:40
executing can you see
19:40
executing can you see this and this is because I
19:44
this and this is because I
19:44
this and this is because I scheduled the job in the Dapper
19:48
scheduled the job in the Dapper
19:48
scheduled the job in the Dapper scheduler remember that Dapper scheduler
19:52
scheduler remember that Dapper scheduler
19:52
scheduler remember that Dapper scheduler service is running as an um Docker
19:57
service is running as an um Docker
19:57
service is running as an um Docker container speaking of which that
20:00
container speaking of which that
20:00
container speaking of which that scheduling information is being stored
20:03
scheduling information is being stored
20:03
scheduling information is being stored in this it City database that is a key
20:07
in this it City database that is a key
20:07
in this it City database that is a key value database quite famous in the
20:10
value database quite famous in the
20:10
value database quite famous in the kubernetes
20:12
kubernetes
20:12
kubernetes ecosystem since this is a database this
20:14
ecosystem since this is a database this
20:14
ecosystem since this is a database this is the same storage that kubernetes uses
20:18
is the same storage that kubernetes uses
20:18
is the same storage that kubernetes uses for um storing the control plane data
20:22
for um storing the control plane data
20:22
for um storing the control plane data and all the things related to that
20:25
and all the things related to that
20:25
and all the things related to that cluster so in a similar fashion the
20:29
cluster so in a similar fashion the
20:29
cluster so in a similar fashion the scheduler is
20:31
scheduler is
20:31
scheduler is storing the jobs in ET CD and that's
20:36
storing the jobs in ET CD and that's
20:36
storing the jobs in ET CD and that's why this is executing and it was
20:39
why this is executing and it was
20:39
why this is executing and it was executing the other um the other jobs
20:43
executing the other um the other jobs
20:43
executing the other um the other jobs that I had
20:47
beforehand so this is great take into
20:51
beforehand so this is great take into
20:51
beforehand so this is great take into account that the diaper schedu or
20:54
account that the diaper schedu or
20:54
account that the diaper schedu or service must be running as I mentioned
20:56
service must be running as I mentioned
20:56
service must be running as I mentioned before
20:59
before
20:59
before and this is important that's why we're
21:03
and this is important that's why we're
21:03
and this is important that's why we're not gonna see
21:05
not gonna see
21:05
not gonna see high in the console again since I
21:10
high in the console again since I
21:10
high in the console again since I replaced the job that I had
21:14
replaced the job that I had
21:14
replaced the job that I had beforehand and this is because when you
21:17
beforehand and this is because when you
21:17
beforehand and this is because when you create a job any existing job with the
21:19
create a job any existing job with the
21:19
create a job any existing job with the same name will be replaced okay makes
21:23
same name will be replaced okay makes
21:23
same name will be replaced okay makes sense
21:25
sense
21:25
sense so that's why it was replaced since I
21:30
so that's why it was replaced since I
21:30
so that's why it was replaced since I was using the same job
21:33
was using the same job
21:33
was using the same job name and if I go back here to the
21:35
name and if I go back here to the
21:35
name and if I go back here to the terminal you can see that this job is
21:38
terminal you can see that this job is
21:38
terminal you can see that this job is executing every
21:43
minute Mak
21:45
minute Mak
21:45
minute Mak sense so this is the jobs
21:48
sense so this is the jobs
21:48
sense so this is the jobs API and the jobs SDK for.net
21:52
API and the jobs SDK for.net
21:52
API and the jobs SDK for.net quite easy to
21:55
quite easy to
21:55
quite easy to use um and you can easily see how to
21:59
use um and you can easily see how to
21:59
use um and you can easily see how to implement this in your own
22:01
implement this in your own
22:01
implement this in your own applications just implement the job
22:06
applications just implement the job
22:06
applications just implement the job itself and then you specify the code
22:08
itself and then you specify the code
22:08
itself and then you specify the code that you want to execute when the
22:12
that you want to execute when the
22:12
that you want to execute when the scheduling kicks

scheduling kicks
22:15
scheduling kicks in
