AWS CodePipeline tutorial | Build a CI/CD Pipeline on AWS
Summary
TLDRThis tutorial guides viewers through building a simple CI/CD pipeline on AWS using AWS CodePipeline. It demonstrates automating the deployment process of a sample Node.js application from GitHub to production on AWS Elastic Beanstalk, which abstracts the use of EC2 instances. The video covers setting up Elastic Beanstalk, creating a CodePipeline, and testing the deployment with a live code change, showcasing the efficiency of automated deployment workflows.
Takeaways
- 😀 The tutorial is about building a simple CI/CD pipeline on AWS using AWS CodePipeline to automate the code release process from local development to production.
- 🔧 The deployment pipeline uses a sample Node.js application located in a GitHub repository and triggers the AWS CodePipeline instance upon commits to the repository.
- 🌐 AWS CodePipeline will deploy the application to a target web server set up on AWS Elastic Beanstalk, which manages EC2 instances behind the scenes.
- 📝 The tutorial provides a link to the 'Musician App' repository, which is a Node.js application with read, write, and delete functionality for a list of musicians.
- 🛠️ Elastic Beanstalk simplifies the deployment of resources to AWS by abstracting the underlying EC2 instances and handling the provisioning of resources.
- 🔄 The process is automated, including the running of 'npm install' if a 'package.json' file is found in the application root.
- 🔑 The tutorial guides through setting up AWS CodePipeline with permissions to access a GitHub account and selecting the appropriate repository and branch.
- 🔍 The use of GitHub webhooks is recommended for an event-driven model where code commits trigger the pipeline, as opposed to a check-and-pull mechanism.
- 🚀 The tutorial demonstrates creating a pipeline named 'Musician App Pipeline' and configuring it to deploy to the same region as the Elastic Beanstalk environment.
- 🔄 After the initial setup, the tutorial shows how to make changes to the application, commit them to GitHub, and verify that the changes trigger a new deployment through the pipeline.
- 🔧 The tutorial concludes with the addition of a health check URL to the application, which returns a 200 OK message, and demonstrates the pipeline's ability to update the production environment with the new code.

Transcripts
hey everyone how's it going and welcome
to another cloud path tutorial today
we're going to be building a simple CI
CD pipeline on AWS using AWS code
pipeline in order to automate our code
release process from local development
all the way out to production so if that
sounds interesting please stick around
and let's do this alright so let's take
a high-level look at what our deployment
pipeline is going to look like
first of all we'll be using a sample
node.js application located in the
github repository we'll set up our
pipeline so that whenever we commit any
changes to our application and github
it'll trigger our AWS code pipeline
instance to kick in and start the
deployment process finally code pipeline
will deploy our application to our
target web server which will be setup an
AWS elastic Beanstalk which essentially
means that our code will live on ec2
instances behind the scenes so that's it
very simple just a simple one stage
build pipeline and it's likely that in
future tutorials we'll add to this
pipeline and you know add a build stage
and possibly some other stages to the
pipeline alright so don't worry too much
if you're not familiar with elastic
beanstalk or code pipeline that's kind
of the point of this video we'll touch
on all those pieces as we go through the
process alright so before we actually
start to build out our pipeline I just
want us to take a quick look at the
sample app that we'll be using as our
target in this exercise so this is the
musician app and it just it's a node.js
application that provides read write and
delete functionality for a list of
musicians here's what it looks like in
the UI okay so we can you know delete
musicians can add a new one
just like that very basic all right just
to give us something to work with here
so in the description of this video I
will provide a link to the musician app
repository here so what I want you guys
to do is either either fork this
application into your own github
repository or you can clone and download
it and upload it to your own github but
whichever way you go about it just make
sure you have a copy of this application
in your own github account alright guys
so I think we're ready to start building
out our pipeline let's go ahead and
navigate to aws.amazon.com and go ahead
and sign into the management console
there we go alright now the first place
I want to go to is elastic Beanstalk so
if you don't have it under recently
visited just go ahead and type it into
the search here elastic Beanstalk there
it is alright so in a nutshell elastic
Beanstalk is just a way for us to deploy
resources to AWS so in this case it's
going to deploy resources to ec2
instances behind the scenes if this were
a real production grade application I
may go directly to ec2 and set it up
directly there just so I have a little
bit more control but at the expense of a
little bit of control this allows us to
deploy resources you know very quickly
so it's perfect for a demo like this now
depending on whether you've been here
before the splash page may look slightly
different I know in some cases you may
see a little drop down here prompting
you to choose your you know what kind of
environment you want to create right off
the bat and then you know you have a
call to action below so if you do see
that go ahead and choose nodejs and then
whatever it is create environment create
application in my case I'm just going to
go ahead and click on get started all
right now either way you should
basically end up at the same place
eventually so I'm gonna give this a name
musician app alright and for platform
I'm gonna choose nodejs since this is a
node.js application I'm going to leave
sample application highlighted I'm not
going to upload or deploy my code at all
at this point because I'm gonna allow
our build pipeline to actually do that
once that setup
all right so once you've made those
selections go ahead and click on create
application all right
now this will take several minutes to
you know provision so I'm gonna go ahead
and pause the video and come back as
soon as this is complete alright that is
now finished so just to recap what have
we actually done here so first we've
created a new environment a node.js
environment and then elastic Beanstalk
has also deployed a sample application
into that environment so we've used
things like ec2 and s3 instances behind
the scenes but you don't really see that
except for looking at the logs because
elastic Beanstalk basically takes care
of all that provisioning of resources
for us
all right now oh the other thing I want
to mention is you don't have to worry
about even adding any kind of build
scripts for for example for NPM install
basically elastic Beanstalk if it finds
it package dot JSON in the root of your
application it will run that for us so
everything about this process is very
automated and automatic which is where
the convenience factor comes in all
right so what we can do is just test to
make sure this is this is all working if
you see at the top of the page it gives
us a URL for the test application that's
been deployed so I'm gonna go ahead and
open that in a new tab and there we go
congratulations your first AWS elastic
Beanstalk node.js application is now
running yadda yadda yadda so our initial
deployment was successful great so now
the next step is going to be to actually
go over to AWS code pipeline and set up
our build pipeline so I'm going to go
ahead and close this for now and let's
see I don't think I need to do anything
else here so let's go back up to
services and I've got code pipeline here
in my history but if you don't you know
what to do just type it in here and it
should pop right up
all right so the first thing I'm going
to do here is go ahead and click on
create pipeline alright and let's make
the screen a little bit bigger here
alright so let's give our pipeline a
name so I'm going to say musician app
pipeline just to keep it consistent here
all right and I'm gonna pretty much
leave all my default set new service
role so this is saying yes please go
ahead and create this iam service role
that's needed so that'll do that behind
the scenes for us
artifacts tour I'll leave is the default
location so if any artifacts are created
as a result of this pipeline it'll
create an s3 bucket to store those in
alright so let's go ahead and click on
next source provider so I'm gonna go
ahead and click on github because that's
where our source code lives now you'll
need to allow AWS permissions to access
your github account so go ahead and
click on connect to github and you'll
probably have to enter in your password
I didn't because I've done this already
so it was pretty quick for me but just
enter in your github password and then
allow permissions to AWS once you've
done that we can select our repository
which is where is it musician app there
it is go ahead and select the master
branch and detect options so this is
basically saying how do you want your
pipeline to be triggered if I select AWS
code pipeline basically it's a kind of
check and pull mechanism or it'll say
have there been any changes know any
changes no any changes no any changes
yes go ahead and kick off the pipeline
but I think using git github web hooks
is much more efficient so it's more of a
event-driven model where anytime you
have a check-in or code commit or merge
it'll go ahead and kick off the pipeline
so let's leave all of our defaults here
selected and click on next build
provider we're actually going to skip
the build stage in this tutorial and
we'll add it in future videos but right
now I think we just want to focus on
getting the deployment complete the
deploy provider is going to be elastic
Beanstalk this is our target all right
and you want to make sure that your
elastic Beanstalk
and your code pipeline are both within
the same region and so make sure that's
selected here application name is going
to be music musician app environment
name is going to be a musician app E&V
it may be without the one for you just
I've done this a couple of times so it
may be slightly different for me all
right click on next so this is our
review page we're just verifying that
everything looks good and go ahead and
click on create pipeline alright so now
we can see that the pipeline has been
created and it is right now deploying to
elastic Beanstalk so the first stage
here was successful now we're deploying
so that should just take a minute or two
and then we can go ahead and verify that
our codes been deployed all right and it
looks like the deployment is complete so
let's go ahead and check that I'm gonna
open up this in a new window oh I think
I just have to click on it there we go
alright so this is our environment our
node.js environment I'm going to click
on that and here's our application
within that environment so there's a URL
up here that we've seen before so let's
just go ahead and open that in a new tab
and there we go there is our deployed
application so we're no longer seeing
that test sample application let's just
quickly make sure this works I'll delete
one and just add somebody ok good and so
cool everything's working alright so
with that that is basically our pipeline
is complete now so what I want to do now
is make a slight change to the
application commit that code and then
let's check and make sure that our
triggering works and that you know that
check in basically triggers another
deployment pipeline and that we finally
see our changes in production alright
alright so I've opened up visual studio
and what I want to do is just make a
small change in the musician app and
then push it and you know see if it
works so what I want to do is add a
health check URL that just returns like
a 200 ok message
so let's go ahead and open up so
underneath musician app underneath the
root folder I'm going to open up routes
and then musician J s and let me make
the font size a little bit bigger here
this is basically where our express
routes are defined oh yeah ctrl + there
we go well that's too big ctrl - alright
so hopefully this will work the first
time haven't actually tested this
beforehand so live coding here so we're
gonna do a get let's go ahead and copy
this first retrieve all and let's just
copy that whole block or sorry paste
that whole block right above it so I'll
just change the comment to say health
check alright and we want to change the
route endpoint to be let's just do
health like that so we don't need this
line musicians we don't need any of this
actually so let's just leave like one
response status just like this and then
so we're gonna send back 200 and let's
just send back a string message and
we'll say 200 okay just so that whenever
we hit this endpoint you know we have
some kind of indication that the server
the server or service is up and running
so I'm gonna go ahead and save that you
know let's just change this to say
status okay it doesn't matter anything
you want so save that alright so I'm
gonna open up a command line interface
here so I can check that in just make
this a little bit bigger here as well
I'm actually running this application
locally so I'm going to exit out of that
clear so I'm going to do a git status
get ad
routes and that should be enough to add
that file okay I'm gonna do a git commit
when I say add health check route okay
and I'm gonna say git push so I'm
pushing that change to the repository
directly to the master branch so
theoretically that should be kicking up
that should be kicking off our code
pipeline process alright so let's go
back to AWS and see what's happening
over there mmm great that looks like
it's working just fine I can see that
you know before I even got to this page
it looks like it already succeeded again
and it's deploying right now to elastic
Beanstalk so far so good I'm just gonna
let this run because it was pretty quick
last time and then what we can do is
just close some of these folders here
I've already got that up and running so
I can close elastic Beanstalk and so
once this finishes we can just do like a
slash health and expect to get back that
string that will be our verification all
right it'll take them I guess that's
gonna take a minute longer so let me
just stop this for now all right
deployment complete so now we can go
back to our application and check that
health check route let's pop open dev
tools just in case anything goes wrong
so we can kind of get some debugging
information here preserve log good
console
all right so actually since we created
this route in the musicians routes file
we have to do slash musicians slash
health you know I'd probably changed
this in a production app just to be
slash health but this is fine for now I
think that's right so let's try that no
it didn't like that for some reason hmm
a musician maybe it's
it's just musician not musicians maybe
cool status okay alright so as you can
see our code changes you know that's
just awesome like I just committed that
to github and it's already in production
so I didn't have to do take any further
action or anything like that
code pipeline just kicked in and worked
it's magic and our code is already alive
so great well you know obviously we're
just scratching the surface here with
what's possible with CI CD and AWS so I
think you know if there's any interest
in this video I'll probably follow up
with a couple of more where we'll
actually add like a build stage and
possibly some other kind of stages into
our pipeline make it a little bit more
robust and sophisticated so but for now
I think this is a good exercise to get
our feet wet here cool well if you guys
enjoyed this video and enjoy my content
in general please consider subscribing
to the channel that helps me out a lot
really appreciate we'd love to have you
and otherwise I will see you in the next
video alright guys take care
