This folder contains the Dockerfile manifests needed to build Debian-based PostgreSQL operand container images for use with CloudNativePG.

The images are based on the official PostgreSQL images on DockerHub.

The folder includes:

• Directories for each supported PostgreSQL version.
• Image catalog files for each Debian version.
• Templates for the main Dockerfile and the beta version Dockerfile (typically identical, except for some extensions that are not ready for the new major release of PostgreSQL).
• The requirements.in file required to build Barman Cloud images. (Note: This file will be removed once a Barman Cloud plugin supporting CNPG-I is distributed.)
• The main update script.

To add a new beta version, follow these steps:

1. Create a new issue in the "postgres-containers" project with the title "Add PostgreSQL XX beta1 images".
2. Clone the postgres-containers repository.
3. Create a new branch named after the issue ID (e.g., dev/YYY).
4. Create the Debian/XX/ directory.
5. Identify the latest Debian version name (e.g., bookworm).
6. Run Debian/update.sh XX -d bookworm which will create a .versions.json file into the Debian/XX/bookworm/ directory.
7. Add the new directory to your commit and push the changes.
8. Run the Automatic updates action on the branch and wait for it to complete (this will add a commit to the branch).
9. Submit a pull request.

• Error while running update.sh

sed: can't read requirements.txt: No such file or directory
cat: requirements.txt: No such file or directory
rm: cannot remove 'requirements.txt': No such file or directory

If a similar error appears, the reason is that you are missing the pip-compile utility that's needed to build the python requirements for Barman Cloud. (Note: This requirement will be removed once a Barman Cloud plugin supporting CNPG-I is distributed.)
