If renovate is set up, it'll add and update the pinned digest/hash of the image.
If renovate is set up for your repo, it'll add and update the pinned digest/hash of the image.
## Development
Generally you should have `Docker` or something alike installed.
If you need to copy files into the container, don't forget to add exclusions to the general _exclude all_ in `.dockerignore`.
To update the base image (like `3.12.4-alpine3.20` to a newer Alpine version), manual work is still required. In the `Dockerfile`, update the Alpine version for the image, the renovate comments (`# renovate: datasource=repology depName=alpine_3_20/gcc versioning=loose`), and the package versions for that OS version from the repo (Like on the [Alpine Package Page for gcc](https://pkgs.alpinelinux.org/packages?name=gcc&branch=v3.20&repo=&arch=x86_64)).
To **update the base image** (like `3.12.4-alpine3.20` to a newer Alpine version), manual work is still required, but supported by a little script. **Renovate might not create a PR for newer image tags.**
1. In the `Dockerfile`, update the Alpine version for the image and the renovate comments (`# renovate: datasource=repology depName=alpine_3_20/gcc versioning=loose`).
```diff
- FROM python:3-alpine3.19@sha256:00c0ffeeacab...
+ FROM python:3-alpine3.20 # You can omit the sha256 digest, the script prints it out
# ...
- # renovate: datasource=repology depName=alpine_3_19/build-base versioning=loose
+ # renovate: datasource=repology depName=alpine_3_20/build-base versioning=loose
ENV BUILD_BASE_VERSION="0.8.15"
# ...
```
1. Now run `./get_pkg_versions.sh`. It pulls the alpine image from the Dockerfile, prints it's digest and the latest packages it could find via `apk` inside that container and prints out the names and versions.
Example output of `./get_pkg_versions.sh` for a new image, which is not yet pulled:
```plain

1. Copy the package versions and update the respective `ENV` with it manually in the `Dockerfile`. You also might add the digest to the base image.
1. Test building the image and you can commit it.
