githubactions

app creation:

• npm install
• npm install --save mocha chai request
• npm test test results:
• https://github.com/amitca71/githubactions/actions
• an email is sent by github action upon build failure deployment prerequisite:
• account on heroku + app + api key
• github secrets: HEROKU_API_KEY (retrieved from https://dashboard.heroku.com/account) HEROKU_APP_NAME (as set on heroku)

production deploymennt:

• script (linux only- not tested):deploy_latest_docker_to_production.sh
• command line: heroku container:release -a hello-amit web

usage examples:

• https://hello-amit.herokuapp.com/
• https://hello-amit.herokuapp.com/?name=amit

app server improvement: separate the start and serve app

test improvement:

• known issue: mocha test with --end, always returns success. not using --end, the process hangs as the server is not being shut down
• solve the always success test case
• add applicative test to check the results
• test with service name and not local host binding

docker improvement:

• use docker cache and push only tagged versions, as described: cache-from: type=local,src=/tmp/.buildx-cache cache-to: type=local,dest=/tmp/.buildx-cache (on: push: tags: - "v*.."

  git tag -a v1.0.2
  git push origin v1.0.2)
  

• known issue: the image that is published to dockerhub is redundant for deployment, and can be removed from the pipeline
