This image is in docker hub under https://hub.docker.com/r/yvess/alpine-apache2-webdav/ you can pull it with docker pull alpine-apache2-webdav:latest.

docker-compose.yml

Here is a example docker-compose.yml file to configure the service, adapt it to your own settings. SSL is optional but almost mandatory for real world usage.

apache2:
  image: yvess/alpine-apache2-webdav:0.1
  hostname: apache2
  environment:
    - SERVER_NAME=myserver
    - CREATE_TESTUSER=YES
    - SSL=YES
    - SSL_KEY=/path_to_key/ssl.key
    - SSL_CERT=/path_to_cert/ssl.crt
    - WWW_DATA_UID=33 # optional
    - WWW_DATA_GID=33 # optional
  volumes:
    - /local_path_to_key/ssl.key:/path_to_key.key
    - /local_path_to_cert/ssl.crt:/path_to_cert.crt
    - ./davshares:/etc/apache2/davshares
    - ./your_path/auth:/etc/auth
    - /your_path/your_dir:/var/www/testuser
  ports:
    - "127.0.0.1:8080:80"
    - "127.0.0.1:8443:443"
    - "127.0.0.1:21:21"
    - "127.0.0.1:21100-21110:21100-21110"

The WWW_DATA_UID and WWW_DATA_GID env vars are optional and set so that it matches the ubuntu default of 33 for the www-data user/group. You need to change this, to match the uid/gid for your share mounts, otherwise the user www-data can't write into your share.

example share conf

You can have multiple shares in the folder davshares (can be changed).

The share file testuser.conf in davshares looks like this.

Alias /testuser "/var/www/testuser"
<Directory "/var/www/testuser">
    Include /etc/apache2/webdav_defaults.conf
    AuthUserFile "/etc/auth/apache2/testuser/users.passwd"
</Directory>

Also mount the shares dir and auth files into the container.

..
    - ./testuser:/var/www/testuser
..

Inside the container you can create password files and share files with following command.

$ create_user.sh -h
usage: create_user_share.sh [-w] [-f] [-s sharename] username] | [-h]
$ create_user.sh testuser

The usernmae:password testuser:testuser is used for testing.
