From 6392365470352c233751b5c99e3772b6e42c1f60 Mon Sep 17 00:00:00 2001 From: Isaac Good Date: Thu, 7 May 2026 23:22:07 -0700 Subject: [PATCH] Pin the Docker image Exercism's policy is to prefer pinned versions. Using the same hash across all runners allows us to store and reuse the same image, rather than needing to store a per-runner base image. This helps cut down on storage costs. --- Dockerfile | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/Dockerfile b/Dockerfile index e11392e..14e6aac 100644 --- a/Dockerfile +++ b/Dockerfile @@ -1,4 +1,4 @@ -FROM ubuntu:24.04 +FROM ubuntu:24.04@sha256:c4a8d5503dfb2a3eb8ab5f807da5bc69a85730fb49b5cfca2330194ebcc41c7b RUN apt-get update --fix-missing RUN apt-get upgrade --yes
