## Get and run a Shaarli image
|
|
|
|
### DockerHub repository
|
|
The images can be found in the [`shaarli/shaarli`](https://hub.docker.com/r/shaarli/shaarli/)
|
|
repository.
|
|
|
|
### Available image tags
|
|
- `latest`: latest branch
|
|
- `master`: master branch
|
|
- `stable`: stable branch
|
|
|
|
The `latest` and `master` images rely on:
|
|
|
|
- [Alpine Linux](https://www.alpinelinux.org/)
|
|
- [PHP7-FPM](http://php-fpm.org/)
|
|
- [Nginx](http://nginx.org/)
|
|
|
|
The `stable` image relies on:
|
|
|
|
- [Debian 8 Jessie](https://hub.docker.com/_/debian/)
|
|
- [PHP5-FPM](http://php-fpm.org/)
|
|
- [Nginx](http://nginx.org/)
|
|
|
|
Additional Dockerfiles are provided for the `arm32v7` platform, relying on
|
|
[Linuxserver.io Alpine armhf
|
|
images](https://hub.docker.com/r/lsiobase/alpine.armhf/). These images must be
|
|
built using [`docker
|
|
build`](https://docs.docker.com/engine/reference/commandline/build/) on an
|
|
`arm32v7` machine or using an emulator such as
|
|
[qemu](https://resin.io/blog/building-arm-containers-on-any-x86-machine-even-dockerhub/).
|
|
|
|

|
Status: Downloaded newer image for shaarli/shaarli:latest
|

```
|
|
|
|
### Create and start a new container from the image
|
|
```shell
|
|
# map the host's :8000 port to the container's :80 port
|
|
$ docker create -p 8000:80 shaarli/shaarli
|
|
d40b7af693d678958adedfb88f87d6ea0237186c23de5c4102a55a8fcb499101
|
|
|
|
# launch the container in the background
|
|
$ docker start d40b7af693d678958adedfb88f87d6ea0237186c23de5c4102a55a8fcb499101
|
|
d40b7af693d678958adedfb88f87d6ea0237186c23de5c4102a55a8fcb499101
|
|
|
|
# list active containers
|
|
$ docker ps
|
|
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
|
|

|
|
```
|
|
|
|
### Stop and destroy a container
|
|
```shell
|
|
$ docker stop backstabbing_galileo # those docker guys are really rude to physicists!
|
|
backstabbing_galileo
|
|
|
|
# check the container is stopped
|
|
$ docker ps
|
|
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
|
|
|
|
# list ALL containers
|
|
$ docker ps -a
|
|
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
|
|
d40b7af693d6 shaarli/shaarli /usr/bin/supervisor 5 minutes ago Exited (0) 48 seconds ago backstabbing_galileo
|
|
|
|
# destroy the container
|
|
$ docker rm backstabbing_galileo # let's put an end to these barbarian practices
|
|
backstabbing_galileo
|
|
|
|
$ docker ps -a
|
|
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
|
|
```
|
|
|
|
### Automatic builds
|
|
Docker users can start a personal instance from an
|
|
[autobuild image](https://hub.docker.com/r/shaarli/shaarli/).
|
|
For example to start a temporary Shaarli at ``localhost:8000``, and keep session
|
|
data (config, storage):
|
|
|
|
```shell
|
|
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](https://docs.docker.com/storage/volumes/).
|
|
Volumes allow to keep your data when renewing and/or updating container images:
|
|
|
|
```shell
|
|
# 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
|
|
```
