I have 3 different repositories which has to be deployed(deploymentType is Blue/Green) to same autoscaling group. I've created 3 different code pipeline and one deployment group.
Problem here is Blue/Green deployment will create new autoscaling group using the AMI-id provided in Launch Template, so at a time only one branch will be there in the instance.
As all 3 repos code is required for the Web App to function. As I don't want to create new autoscaling groups for all 3 repos. I thought of doing it like this:
Dummy Branch A:
ProjectName
- Repo1Project
- Repo2Project
- Repo3Project
- appspec.yml
- attach-target-group-to-alb.sh
and in appspec.yml:
version: 0.0
os: linux
files:
- source: ProjectName/Repo1Project
destination: /var/www/html/Repo1Project
- source: ProjectName/Repo2Project
destination: /var/www/html/Repo2Project
- source: ProjectName/Repo3Project
destination: /var/www/html/Repo3Project
hooks:
BeforeInstall:
- location: Repo1Project/Scripts/pre_install.sh
- location: Repo2Project/Scripts/pre_install.sh
- location: Repo3Project/Scripts/pre_install.sh
timeout: 600
runas: ec2-user
AfterInstall:
- location: Repo1Project/Scripts/post_install.sh
- location: Repo2Project/Scripts/post_install.sh
- location: Repo3Project/Scripts/post_install.sh
timeout: 600
runas: ec2-user
AfterAllowTraffic:
- location: attach-target-group-to-alb.sh
timeout: 600
runas: ec2-user
Update each folder by using this command:
To merge only specific file/folder from other branch to current
git checkout Repo1ProjectBranch ProjectName/Repo1Project
git commit -m "Your comment"
And then push it to actual BranchB
But I'm not sure if this is valid way of doing it, or there is any other better solution. So thought of posting it here if anyone has already found better solution.
