[Feature]: warn users if running a deprecated/unsupported Debian version #8575
Description
Is there an existing issue already for this feature request/idea?
- I have searched for an existing issue, and could not find anything. I believe this is a new feature request to be evaluated.
What problem is this feature going to solve? Why should it be added?
The postgres-containers project now includes a table that clearly outlines the support status of various Debian versions:
| Name | Version | Release Date | EOL | LTS | Status |
|---|---|---|---|---|---|
Trixie (stable) |
13 | 2025-08-09 | 2028-08-09 | 2030-06-30 | Supported |
Bookworm (oldstable) |
12 | 2023-06-10 | 2026-06-10 | 2028-06-30 | Supported |
Bullseye (oldoldstable) |
11 | 2021-08-14 | 2024-08-14 | 2026-08-31 | Deprecated |
We should implement a warning that activates when the cluster starts up, indicating if a version is beyond its End of Life (EOL) status (deprecated) or beyond its Long-Term Support (LTS) period (not supported).
Describe the solution you'd like
Verify the content of the /etc/os-release file which, in the case of bullseye reports this:
$ kubectl exec -ti cluster-example-1 -c postgres -- cat /etc/os-release
PRETTY_NAME="Debian GNU/Linux 11 (bullseye)"
NAME="Debian GNU/Linux"
VERSION_ID="11"
VERSION="11 (bullseye)"
VERSION_CODENAME=bullseye
ID=debian
HOME_URL="https://www.debian.org/"
SUPPORT_URL="https://www.debian.org/support"
BUG_REPORT_URL="https://bugs.debian.org/"
CloudNativePG could maintain an internal table where the VERSION is the key, storing the two dates (supported_until and deprecated_from). Based on the current date at the time of startup of the PostgreSQL instance, the instance manager can log a warning as explained above.
