AWS Code Deploy - CI/CD Series Part 3

-

 

AWS Code Deploy is a service provided by Amazon Web Services (AWS) that helps you automate software deployment on various types of computing resources such as EC2 instances, on-premises servers, or Lambda functions.

Appspec.yaml:

The AppSpec file is a YAML-formatted file used by AWS CodeDeploy to manage the deployment of an application.

It provides instructions to CodeDeploy about the application’s source code, the deployment target, the scripts to run, and the permissions required to execute the scripts.

It also includes information about the deployment lifecycle hooks, which allow developers to execute custom scripts at specific points during the deployment process.

Before we start with code deploy, We need to create a role which has the below permissions.


Once the role is created. Let's proceed to Code Build. Create an application.

Next, Create a deployment group for the application.

Give the deployment group name and role that we created and select the deployment type. I have chosen "InPlace" update.



In environment configuration, I am selecting "EC instance" by the name "demo". So, I should have an EC2 instance by the name "demo" with code deploy agent installed. Refer to this link for installing code deploy agent https://docs.aws.amazon.com/codedeploy/latest/userguide/codedeploy-agent-operations-install-ubuntu.html



Once the deployment group is created. Proceed with creating a deployment. 


Under deployment, select the deployment group. 


Enter the source where the build(artifacts) are available - S3. Give the bucket name and file extension.




Click on "Create Deployment" and "Start Deployment".


Our deployment is completed, which means our app is installed on the EC2 instance and we can test it by accessing the IP of the EC2 instance.



In the next post, We will Code PipeLine.

  This is a multi-part series to show how to implement a CI/CD pipeline in AWS. In this post, We will see how to use AWS Code Commit. AWS CodeCommit is a fully managed source control service that allows you to store and manage your code securely in the cloud.  It provides a private Git repository for your code and supports all Git commands and workflows. CodeCommit also integrates with other AWS services like AWS CodePipeline and AWS CodeBuild, allowing you to automate your entire software release process. This can help you streamline your development workflows and improve the overall efficiency of your team. I created a repo from AWS CodeCommit -> Create Repository. And I begin with cloning the repo locally. So that I can make changes and push it. To clone the repo click on "HTTPS" under Clone URL. I make changes to index.html file. Now push it to AWS CodeCommit. Let’s verify the changes in AWS Code commit. Changes are reflected in AWS CodeCommit. We are done with Part ...

Docker - Preventing IP overlapping

  What is IP address overlapping? When the container IP address overlaps with another IP external, then the application running on the container is not accessible from outside due to the IP address overlapping.  NOTE: This IP address overlapping can happen on the bridge interface IP or docker container IP. Let's see how to address this IP overlapping issue on the bridge interface. I already have a running container.  root@demo:~# docker run -d --name web --network mynet1 nginx:alpine 268647e11011d513d2357ce1c81e0f48787038a83d01d028d31a5b29dbdb885b root@demo:~# docker container ls CONTAINER ID   IMAGE          COMMAND                  CREATED         STATUS         PORTS     NAMES 268647e11011   nginx:alpine   "/docker-entrypoint.…"   4 seconds ago   Up 3 seconds   80/tcp  ...
