There are two components to using GitHub Actions that we'll cover:
A workflow can contain many actions, but each action has its own purpose. So, we'll put the files relating to the action in their own directory.
Dockerfile
Actions come in two types: container actions and JavaScript actions. Our action will use a Docker container so it will require a Dockerfile
. Let's add it now. We won't discuss what each line means in detail, but the important thing to know is that the action will be executed in an environment defined by this file.
Dockerfile
and open a pull requestaction-a/Dockerfile
by using this quick link or manually:
first-action
.action-a
. Note: If you're working on GitHub.com, you can create a directory and a file at the same time by naming the file action-a/Dockerfile
.action-a
directory, create a file titled Dockerfile
.Fill the Dockerfile
with the content below:
FROM debian:9.5-slim
LABEL "com.github.actions.name"="Hello World"
LABEL "com.github.actions.description"="Write arguments to the standard output"
LABEL "com.github.actions.icon"="mic"
LABEL "com.github.actions.color"="purple"
LABEL "repository"="http://github.com/octocat/hello-world"
LABEL "homepage"="http://github.com/actions"
LABEL "maintainer"="Octocat <octocat@github.com>"
ADD entrypoint.sh /entrypoint.sh
RUN chmod +x /entrypoint.sh
ENTRYPOINT ["/entrypoint.sh"]
master
