As pootle consists of multiple components, we provide a docker-compose.yml to bring up and connect all the services.
Use the following command to bring up the environment:

docker-compose up -d

Notice: The mysql-server and the redis cache are not accessible by the outside world. Only the pootle container can access those services.

On the first run you must setup your database and create an admin user.

docker-compose exec pootle bash
pootle migrate
pootle initdb
pootle createsuperuser
pootle verify_user --all

First you must create a project in the pootle administration backend. Only super-users can access the backend. By naming convention, your project in pootle must be named TYPO3.ext.myextname if your extension name is myextname.
As file-type choose XLIFF (.xlf) and leave the other settings default.

All extensions must be placed under /srv/pootle/git-clones/repos in order to be imported and maintained by the pootle server. In order to get the files there you can either add a SFTP container that has access to a specific repo folder e.g.

sftp:
    image: atmoz/sftp
    volumes:
        - /host/share:/home/foo/share
    ports:
        - "2222:22"
    command: foo:123:1001    

Or you place a shell script that automatically updates the project in /srv/pootle/git-clones/scripts/myextname.sh that can do e.g. git clone, download, or whatever to get the files to the repos/myextname folder.
