acmetool Docker container

Uses anacron to run acmetool daily.

Instructions:

Build image:

$ docker build .

Set ACME_STATE_DIR:

$ export ACME_STATE_DIR=$PWD/acme

Create anacron spool:

$ mkdir -p $ACME_STATE_DIR/anacron

Initialize acmetool:

$ ./acmetool quickstart
$ ./acmetool want mydomain.example.com --no-reconcile

Note: Do not create hooks or cronjobs. Select 'Stateless' challenge mode at this stage, even if you are going to use some other method.

Configure challenge mode(s):

$ vi $ACME_STATE_DIR/conf/target
$ cat $ACME_STATE_DIR/conf/target 
request:
  provider: https://acme-staging.api.letsencrypt.org/directory
  challenge:
    webroot-paths:
      - /var/lib/acme/webroot
  key:
    type: rsa

Configure your webserver

Run container:

$ docker run -v $ACME_STATE_DIR:/var/lib/acme image_id

Reload web server configuration manually

Reload hooks are work in progress. Adventurous people can put their hooks into reload file
