GitHub Actions is a continuous integration and continuous delivery (CI/CD) platform that allows you to automate your build, test, and deployment pipeline. You can create workflows that build and test every pull request to your repository, or deploy merged pull requests to production.
GitHub Actions makes it easy to automate all your software workflows. Build, test, and deploy your code right from GitHub. Make code reviews, branch management, and issue triaging work the way you want.
I came up with the idea that the GitHub Actions will work if we use workflow automation including issue triaging. Also, it is completely free if we push it into the public repository!
We can program it to meet our needs by making a YAML file.
See GitHub Actions config yaml for a better understanding.
1. Cron Job, i.e., Scheduled job # every 30 minutes
on:
schedule:
- cron: '*/30 * * * *'
2. Step 1: Check out the repository
This action checks out your repository under $GITHUB_WORKSPACE, so your workflow can access it.
3. Step 2: Install OS(Ubuntu) dependencies(programs for R packages)
Using the premade action(awalsh128/cache-apt-pkgs-action@latest) that caches installed packages from the last run, we can save a lot of time
- name: Install Ubuntu dependencies
uses: awalsh128/cache-apt-pkgs-action@latest
with:
packages: >-
libcurl4-openssl-dev
version: 1
4. Step 3: Install R
- name: Install R
uses: r-lib/actions/setup-r@v2
5. Step 4: Install R dependencies(R packages)
Using the premade action(r-lib/actions/setup-renv@v2) that caches installed packages from the last run, we can save a lot of time
I used the renv package to manifest and clone the environment
- name: Install R dependency
uses: r-lib/actions/setup-renv@v2
with:
profile: '"packages"'
cache-version: 2
6. Step 5: run the main program
name: run main.R
$$\vdots$$
run: Rscript --verbose main.R #run main
7. Step 6~7: steps for sending discord messages
