CA Certificate Container for Docker

A quick note:

This project provides you with an alpine image that keeps your ca-certificates up2date. It also allows you to add custom certificates to use in all of your docker containers, which is useful if you use a registry with a self-signed certificate.


Run it

First you need to create a data-only container, which will share you cert-data over all containers.

docker create --name cert philippheuer/docker-certificates

How to update the RootCA:

docker run -it --rm --volumes-from cert philippheuer/docker-certificates ca-update

To use custom certificates, you need to mount them at /etc/ssl/certs_custom/CERTNAME.crt and it will be appended to the root certificate file by running the ca-update script.

docker run -it --rm \
  --volumes-from cert \
  --volume /LOCALPATH/file.crt:/etc/ssl/certs_custom/file.crt \
  philippheuer/docker-certificates ca-update

How to use

Now you need to append the following part when you create your containers --volumes-from cert:ro. This will mount the ca-certificates.crt in read-ony mode.


docker run -it --rm --volumes-from cert:ro alpine sh
