From 45071cba6f0afd172c22a61aec1186ab5086b84d Mon Sep 17 00:00:00 2001 From: Alberto Bertogli Date: Sun, 1 Feb 2026 10:48:52 +0000 Subject: [PATCH] docker: Use a specific Debian version When Debian releases a new stable version, there could be breaking changes that mean Docker build stops working. New Debian stable versions are infrequent enough that it is better to just do them by hand, to avoid accidentally breaking builds (and subsequently having to fix them in a rush). Thanks to Ernesto Alfonso (erjoalgo@github) for reporting this problem in https://github.com/albertito/chasquid/issues/80. --- docker/Dockerfile | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) diff --git a/docker/Dockerfile b/docker/Dockerfile index 73af700..98dd135 100644 --- a/docker/Dockerfile +++ b/docker/Dockerfile @@ -15,7 +15,10 @@ RUN go get -d ./... && \ go install ./... # Create the image. -FROM debian:stable-slim +# Use a specific Debian stable version, because the move between +# different stable version may introduce some breaking changes, so we want to +# do them in a controlled way. +FROM debian:13-slim # Create the chasquid and dovecot users with fixed UID/GID. # Install the packages we need.
