Sharing data between jobs within a workflow What if you want to share that value with different jobs? This is what will make it available as an environment variable to the steps that follow it. The key bit is that it is sent to the $GITHUB_ENV file. These two blocks should be equivalent, but the expressions mean I generally use the JS version. A minimal demonstration of this is:Įnter fullscreen mode Exit fullscreen mode This is done by sending a statement setting it to the $GITHUB_ENV file. If one of your steps has an output that you need in a later step within the same job you can set it as an environment variable. Inputs to workflows however can be string, number or boolean types. if: env.isTag = 'true' would work, but if: env.isTag alone would not. It's worth baring in mind that because most of what follows uses environment variables under the hood it is a string, so even though the value could be 'true' or 'false' you would need an expression that explicitly compares it to those values. All the information is there, but spread across multiple pages and can take quite a while to put it all together. This was one of the bits that I felt the documentation didn't explain clearly enough. Steps are either actions or shell commands.Jobs are combinations of steps that are run on a virtual machine, they can even be a workflow of their own.If you've been through the Quickstart for GitHub Actions and Understanding GitHub Actions documentation but still have some questions I'm hoping this post will answer some of them. I've written this guide to try and fill in those gaps. I've been using different build systems for years, but after playing with github actions quite a bit there was still some things that I was only managing based on trial and error.
