Run acme.sh in docker

acme.sh 💕 docker

As one of the big docker fans, I understand that we hate installing anything on a docker host, even if it's just copying a shell script.

Automated nginx reverse proxy docker image with acme.sh for letsencrypt ssl cert: https://github.com/Neilpang/letsproxy

Deploy to a docker container and reload it: https://github.com/Neilpang/acme.sh/wiki/deploy-to-docker-containers

So, Here "acme.sh in docker" comes.

1. Based on alpine, only 5MB size.
2. Either run as executable or run as daemon
3. Support all the command line parameters.

1. Say "Hello World"

docker run --rm neilpang/acme.sh

2. Used as an executable:

docker run --rm  -it  \
  -v "$(pwd)/out":/acme.sh  \
  --net=host \
  neilpang/acme.sh  --issue -d example.com  --standalone

You can use any commands that acme.sh supports here, other examples:

#revoke a cert
docker run --rm  -it  \
  -v "$(pwd)/out":/acme.sh  \
  --net=host \
  neilpang/acme.sh  --revoke -d example.com

#use dns mode
docker run --rm  -it  \
  -v "$(pwd)/out":/acme.sh  \
  neilpang/acme.sh  --issue --dns -d example.com

#run cron job
docker run --rm  -it  \
  -v "$(pwd)/out":/acme.sh  \
  --net=host \
  neilpang/acme.sh  --cron

Anyway, you can just invoke neilpang/acme.sh image as if it were a real shell script.

3. Run acme.sh as a docker daemon.

1. Running acme.sh as a docker daemon, so that it can handle the renewal cronjob automatically.

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

Or run acme.sh by using Docker Compose.

Edit docker-compose.yml:

services:
  acme-sh:
    image: neilpang/acme.sh
    container_name: acme.sh
    volumes:
      - ./out:/acme.sh
    network_mode: host
    command: daemon
    stdin_open: true
    tty: true
    restart: no

Then run acme.sh:

docker compose up -d

2. Then you can just use docker exec to execute any acme.sh commands.

docker exec acme.sh --help

docker exec acme.sh --issue -d example.com --standalone

Yes, again, You can use any commands that acme.sh supports here.
