 # based-alpine
+
+This image is based on `node:alpine` with the following additional packages
+available:
+
+- `bash`
+- `curl`
+- `git`
+- `coreutils`
+- `uv`
+
+These are the dependencies I install most commonly in workflows -- so it made
+sense for me to create an image containing them. I use it to make creating new
+Forgejo actions simpler. On my instance [git.ficd.sh](https://git.ficd.sh),
+where I've configured an additional label in the runner, I only need to add the
+following:
+
+```yaml
+runs-on: based-alpine
+```
+
+To run it yourself:
+
+```sh
+docker run --rm -it git.ficd.sh/ficd/based-alpine:latest bash
+```
