A brief guide on getting starting using docker is given in Docker 101. To learn more about user data and how to keep it across versions, please see Upgrade and Migration.

Get and run a Shaarli image

DockerHub repository

The images can be found in the shaarli/shaarli repository.

Available image tags

• latest: latest branch
• master: master branch
• stable: stable branch

The latest, master and stable images rely on:

• Alpine Linux
• PHP7-FPM
• Nginx

Additional Dockerfiles are provided for the arm32v7 platform, relying on Linuxserver.io Alpine armhf images. These images must be built using docker build on an arm32v7 machine or using an emulator such as qemu.

Create and start a new container from the image

# map the host's :8000 port to the container's :80 port
$ docker create -p 8000:80 shaarli/shaarli

# launch the container in the background
$ docker start d40b7af693d678958adedfb88f87d6ea0237186c23de5c4102a55a8fcb499101

Stop and destroy a container

$ docker stop backstabbing_galileo  # those docker guys are really rude to physicists!

Automatic builds

Docker users can start a personal instance from an autobuild image. For example to start a temporary Shaarli at localhost:8000, and keep session data (config, storage):

MY_SHAARLI_VOLUME=$(cd /path/to/shaarli/data/ && pwd -P)
docker run -ti --rm \
         -p 8000:80 \
         -v $MY_SHAARLI_VOLUME:/var/www/shaarli/data \
         shaarli/shaarli

Volumes and data persistence

Data can be persisted by using volumes. Volumes allow to keep your data when renewing and/or updating container images:

# Create data volumes
$ docker volume create shaarli-data
$ docker volume create shaarli-cache

# Create and start a Shaarli container using these volumes to persist data
$ docker create \
    --name shaarli \
    -v shaarli-cache:/var/www/shaarli/cache \
    -v shaarli-data:/var/www/shaarli/data \
    -p 8000:80 \
    shaarli/shaarli:master
$ docker start shaarli
