deploy to docker containers

Deploy the cert/key into a docker container.

There are 3 cases that acme.sh can deploy the certs into containers.

1. acme.sh is installed in the docker host machine, it deploys the certs into a container on the machine.
2. You are running neilpang/acme.sh container, that means acme.sh is running in a container, it can also deploy certs to another container on the same machine.
3. acme.sh is running on a machine, it deploys certs to a container running on another docker host.

Lets explain one by one:

1. Deploy certs from docker host to a container

acme.sh is installed on the docker host, it first issues a cert, then you may want to deploy the cert/key into a container.

1. Please set a label on the container, the label will later be used to find the container.

docker run --rm -it -d  --label=sh.acme.autoload.domain=example.com   nginx:latest

2. Remember the label value above, we can deploy now:

# The label value to find the container
export DEPLOY_DOCKER_CONTAINER_LABEL=sh.acme.autoload.domain=example.com

# The target file path in the container.
# The files will be copied to the position in the container.
export DEPLOY_DOCKER_CONTAINER_KEY_FILE="/etc/nginx/ssl/example.com/key.pem"
export DEPLOY_DOCKER_CONTAINER_CERT_FILE="/etc/nginx/ssl/example.com/cert.pem"
export DEPLOY_DOCKER_CONTAINER_CA_FILE="/etc/nginx/ssl/example.com/ca.pem"
export DEPLOY_DOCKER_CONTAINER_CA_FILE="/etc/nginx/ssl/example.com/ca.pem"
export DEPLOY_DOCKER_CONTAINER_FULLCHAIN_FILE="/etc/nginx/ssl/example.com/full.pem"

# The command to reload the service in the container.
export DEPLOY_DOCKER_CONTAINER_RELOAD_CMD="service nginx force-reload"

acme.sh --deploy --deploy-hook docker -d example.com

2. Deploy certs from a container to another container

Let's use neilpang/acme.sh image as an example, actually, you can use acme.sh in any container.

1. Ok, same as above, first run the target container with a label:

docker run --rm -it -d  --label=sh.acme.autoload.domain=example.com   nginx:latest

2. Run acme.sh in a container

For more details see: https://github.com/Neilpang/acme.sh/wiki/Run-acme.sh-in-docker#3-run-acmesh-as-a-docker-daemon

Let's run acme.sh as a daemon, a difference with the above link is that we mount docker daemon socket /var/run/docker.sock in to the container.

docker run --rm  -itd  \
  -v "$(pwd)/out":/acme.sh  \
  --net=host \
  --name=acme.sh \
  -v /var/run/docker.sock:/var/run/docker.sock \
  neilpang/acme.sh daemon
