docker: upgrade base images to debian:13

2026-11-01T10:06:28Z

Debian 11 (Bullseye) LTS support ends on August 31, 2026. Upgrading to Debian 13 (Trixie) ensures long-term support until June 30, 2030. While upgrading: - Replace deprecated libncurses5-dev package with libncurses-dev. - Install gnupg explicitly as it is no longer pre-installed. - Add legacy-cgi to pip packages. Debian 13 comes with Python 3.13, which removed the standard cgi module. Buildbot 3.11.8 / Twisted requires cgi at startup, so legacy-cgi is required as a drop-in replacement.

ci: rename OPENWRT_VERSION to BUILDBOT_CONFIG_SHA

2026-01-11T20:52:45Z

The old name was misleading as it suggested an OpenWrt release version. The variable holds the git SHA of this buildbot config repository, used for quick URL links to the configuration commit. Signed-off-by: Petr Štetiar

ci: add container version tag to BUILDWORKER_DESCRIPTION

2026-01-11T20:52:36Z

Add CONTAINER_TAG build argument to indicate whether the container was built from a tag (v25), PR (pr-73), or branch (main). This makes it easier to identify which version of the container is running. While at it, drop Docker prefix to make it shorter. Signed-off-by: Petr Štetiar

docker: fix Dockerfile deprecation warnings

2026-01-11T14:30:44Z

Replace deprecated MAINTAINER instruction with LABEL and update ENV statements from legacy "ENV key value" format to "ENV key=value" format. Signed-off-by: Petr Štetiar

docker,worker: install python3-cryptography

2024-11-25T10:12:20Z

Addition of OPTEE support along with STM32 added a requirment on python3-cryptography and without it buildbots for STM32 will fail with: Checking 'python3-cryptography'... failed. Checking 'python3-pyelftools'... ok. optee-os: Please install the Python3 cryptography module make[3]: *** [/builder/shared-workdir/build/include/prereq.mk:9: prereq] Error 1 So install python3-cryptography to satisfy it.

This reverts commit 3ac7d39bd4c364d76e78b3ba50c23a68e0b05c0f as it was decided to stay on Debian 11 for 24.10 release as well. Signed-off-by: Petr Štetiar

buildworker: start: fix broken non TLS setups

2024-11-04T06:12:04Z

Changes in commit 3812ff7bb296 ("buildworker: start: fix worker startup failure after update") broke non TLS setups. So lets fix it by setting SSL: only if BUILDWORKER_TLS is set.

buildworker: start: fix leaking BUILDWORKER_TLS env variable

2024-09-28T17:17:50Z

I've noticed leakage of BUILDWORKER_TLS environment variable in build logs, so lets fix it in a generic way via new `cleanup_buildworker_env_variables()` by using Bash's parameter expansion and unset all environment variables starting with BUILDWORKER_ prefix. Signed-off-by: Petr Štetiar

docker: buildworker: add missing file package

2024-09-27T07:39:12Z

In Debian 11 (Bullseye), the `file` package was installed indirectly because the `man-db` package recommended it. The `man-db` package is often installed as a dependency of other packages, such as `build-essential` and tools like `gcc` and `make`. By default, `apt-get` installs recommended packages, so `file` was installed automatically. Starting from Debian 12 (Bookworm), the `man-db` package no longer recommends the `file` package. This change was made to reduce the size of minimal container images and installations where `file` is not essential. So lets install this package explicitly. Signed-off-by: Petr Štetiar
