Adding TLS certificates in CHT 4.x
To load your certificates into your CHT instance, we’ll be creating an interstitial container called cht-temp-tls
which will enable you to copy your local certificate files into the native docker volume.
Prerequisites
You have two files locally on your workstation in the directory you’re currently in:
key.pem
- the private key for your TLS certificatechain.pem
- both the public and any interstitial keys concatenated into one file
Also, be sure you have started your CHT instance once and all your volumes are created.
Loading the certificate
Note
docker compose
should work, but you may need to use the older style docker-compose
if you get an error docker: 'compose' is not a docker command
.Find the name of your
cht-ssl
volume with this call:docker volume ls --filter "name=cht_" | grep cht-ssl
It is very likely that
cht_cht-ssl
is the name of ourcht-ssl
volume.Using the volume name found in step 1, start a container called
temp
which allow us to copy files into the docker volume:docker run -d --rm --name temp -v cht_cht-ssl:/etc/nginx/private/ alpine tail -f /dev/null
Copy the two pem files into the volume via the temporary container:
docker cp key.pem temp:/etc/nginx/private/. docker cp cert.pem temp:/etc/nginx/private/.
Stop the
temp
container:docker kill temp
Your certificates are now safely stored in the native docker volume. Restart your CHT instance the way you started it, being sure to set the correct CERTIFICATE_MODE
and SSL_VOLUME_MOUNT_PATH
per the prerequisites.
