manoj23 / dockerfile-ca-certificates

Dockerfile that provides a volume of ca-certificates updated weekly

dockerfile-ca-certificates

This is a simple alpine container that maintains the certificates updated every week. Thus, the volume ca-certificates-etc-ssl can be shared with other containers. The volume ca-certificates-var-cache-apk is needed in order to avoid fetching the apk index every time.

Example of docker run

docker build https://github.com:/manoj23/dockerfile-ca-certificates.git -t ca-certificates
docker volume create ca-certificates-etc-ssl
docker volume create ca-certificates-var-cache-apk
docker run --rm -ti
	-v ca-certificates-etc-ssl:/etc/ssl/
	-v ca-certificates-var-cache-apk:/var/cache/apk
	--name ca-certificates ca-certificates

Example of docker-compose.yml

Put in a folder:

• docker-compose.yml as below

version: '3'
services:
  ca-certificates:
    build: https://github.com:/manoj23/dockerfile-ca-certificates.git
    volumes:
      - ca-certificates-etc-ssl:/etc/ssl/
      - ca-certificates-var-cache-apk:/var/cache/apk

volumes:
  ca-certificates-etc-ssl:
  ca-certificates-var-cache-apk:
