#Spring music on concourse

• Concourse
• Build only once and deploy anywhere
• Every build is a release candidate
• Every build step runs inside a docker container mounting to garden linux cells

Resources

Resources in concourse are implemented as docker images which contain implementations corresponding their types

• music-repo (git-resource): A github repo. E.g. spring music github resource

• version (semver-resource): A file to track the version stored in s3. E.g. 1.0.1 in a file named as current-version

• music-release ((s3-resource)) A bucket in s3 that stores spring-music artifact E.g. spring-music-1.0.1.war

Pipeline Progress

Check out from the music-repo

Unit testing spring-music

This step runs on a container with gradle and java installed. Basically it just runs "gradle test" against the music-repo

Build Binary

• music-repo - Check out the same source version of music-repo as unit step
• version - Checkout the version file from s3
• "gradle assemble" generates the war artifact
• Push the artifact to the s3 resource as music-resource
• Git tag on the music-repo
• Bump the version resource for the next usage

acceptance-tests

• Pull the binary from music-release
• Deploy to cloudfoundry acceptance tests space
• Run Automation Acceptance Tests suite

promote-to-uat

• Pull the binary from music-release
• Deploy to cloudfoundry uat space
• Waiting for user acceptance tests

manual-deploy-to-prod

• Manually trigger the build when the operators are ready
• Pull the binary from music-release
• Deploy to prod

How to replicate this pipeline in your env

• Install a concourse environment and fly cli

• Fork this github repo to your own github account, generate the key pair and add the public key to github , and save the private key for future usage.

• Prepare a s3 bucket named as music-pipeline-artifacts

• fly command line dance

--password my-password my-target```

• Configure the cloudfoundry target environment in spring-music.yml E.g.

  API_ENDPOINT: api.10.65.233.228.xip.io
  USERNAME: admin
  PASSWORD: admin
  ORG: test-org
  SPACE: prod
  HOST: music
  

• fly -t my-target configure --config spring-music.yml --var "music_private_key=$(cat PRIVATE_KEY_FOR_GITHUB)" --var s3-access-key-id=YOUR_S3_ACCESS_KEY_ID --var s3-secret-access-key=YOUR_S3_ACCESS_KEY --paused=false spring-music
