- 24. A bit more setup 24 Local Host / CI Host Setup SSH keys Remote Build Host ● OTP ● Elixir ● git ● build-essential ● libssl-dev Remote Deploy Targets ● NOTHING!
- 25. Build a release $ mix edeliver build release BUILDING RELEASE OF CLIPPYX APP ON BUILD HOST -----> Authorizing hosts -----> Ensuring hosts are ready to accept git pushes warning: more than one branch.master.remote -----> Pushing new commits with git to: ubuntu@ec2...us-west-2.compute.amazonaws.com -----> Resetting remote hosts to 79e8c15c8b35803924c6658dc8ec2941637d80a7 -----> Cleaning generated files from last build -----> Fetching / Updating dependencies -----> Compiling sources -----> Generating release -----> Copying release 0.1.0 to local release store -----> Copying clippyx.tar.gz to release store RELEASE BUILD OF CLIPPYX WAS SUCCESSFUL! $ mix edeliver build upgrade --from=<git tag or revision>
- 26. Deploy a release $ mix edeliver deploy release to production DEPLOYING RELEASE OF CLIPPYX APP TO PRODUCTION HOSTS -----> Authorizing hosts -----> Uploading archive of release 0.1.0 from local release store -----> Extracting archive clippyx_0.1.0.tar.gz DEPLOYED RELEASE TO PRODUCTION! RELEASE BUILD OF CLIPPYX WAS SUCCESSFUL! $ mix edeliver upgrade production
- 27. Administration $ mix edeliver start production EDELIVER CLIPPYX WITH START COMMAND -----> starting production servers production node: user : ubuntu host : ec2-54-202-189-109.us-west-2.compute.amazonaws.com path : /home/web response: success START DONE! $ mix edeliver update production --start-release
- 28. Administration mix edeliver stop production mix edeliver restart production mix edeliver ping production mix edeliver version production mix edeliver show migrations on production mix edeliver migrate production
- 29. Things to look out for ● Distillery 1.0+ output_dir ● Race condition on slow hosts
