12. Write Simple Workflow
13. |-- hello-world (repository) | |__ .github | |__ main.workflow |
14. workflow "Remote ssh commands" { on = "push" resolves = [ "Remote ssh commands", ] } main.workflow
15. action "Remote ssh commands" { uses = "appleboy/ssh-action@master" secrets = [ "HOST", "PASSWORD", ] args = [ "--user", "actions", "--script", "whoami", ] } main.workflow

24. Secrets in Github Actions Setting -> Secrets in left sidebar
26. action "Remote ssh commands" { uses = "appleboy/ssh-action@master" secrets = [ "HOST", "PASSWORD", ] args = [ "--user", "actions", "--script", "whoami", ] } main.workflow
27. What’s problem in Secrets?
28. Don’t support organization secrets duplicate of secrets in many repository of organization
29. Don’t support thirty party secret service
30. You need to write CLI flag in command drone-ssh -u foo -p foopass -s whoami drone-ssh -u bar -p barpass -s whoami
31. main.workflow secrets = [ "PASSWORD", ] args = [ "--user", "actions", "--script", "whoami", ] secrets = [ "PASSWORD", ] args = [ "--user", "actions", "--script", "whoami", ] 4FSWFS

33. action "Publish" { needs = "Tag" uses = "actions/npm@master" args = "publish --access public" secrets = ["NPM_AUTH_TOKEN"] } IUUQTHJUIVCDPNBDUJPOTOQN
34. How to add multiple auth token of npm registry?
35. kind: pipeline name: default steps: - name: build image: appleboy/drone-ssh environment: USERNAME: from_secret: username PASSWORD: from_secret: password
36. Creating GitHub Actions
37. |-- ssh-action (repository) | |__ .github | |__ main.workflow | |__ Dockerfile | |__ entrypoint.sh | |__ README.md | |__ LICENSE
38. Support any language you want
39. Dockerfile
40.

41. entrypoint.sh
42. #!/bin/sh set -eu export GITHUB="true" sh -c "/bin/drone-ssh $*"
43. action "Tag Docker Image" { needs = ["build"] uses = "actions/docker/cli@master" args = "tag hello:$GITHUB_SHA" }
44. action "Tag Docker Image" { needs = ["build"] uses = "actions/docker/cli@master" args = ["tag", "hello:$GITHUB_SHA"] }
45. Environment variables
46. action "Hello World" { uses = "./my-action" env = { FIRST_NAME = "Mona" MIDDLE_NAME = "Lisa" LAST_NAME = "Octocat" } }
47. runtime environment
