1## Basics
2Install [Docker](https://www.docker.com/), by following the instructions relevant
3to your OS / distribution, and start the service.

5### Search an image on [DockerHub](https://hub.docker.com/)
6
7```bash
8$ docker search debian

16### Show available tags for a repository
17```bash

52### Pull an image from DockerHub
53```bash
54$ docker pull repository[:tag]
55
56$ docker pull debian:wheezy
57wheezy: Pulling from debian
584c8cbfd2973e: Pull complete
5960c52dbe9d91: Pull complete
60Digest: sha256:c584131da2ac1948aa3e66468a4424b6aea2f33acba7cec0b631bdb56254c4fe
61Status: Downloaded newer image for debian:wheezy
62```
63
64Docker re-uses layers already downloaded. In other words if you have images based on Alpine or some Ubuntu version for example, those can share disk space.
65
66### Start a container
67A container is an instance created from an image, that can be run and that keeps running until its main process exits. Or until the user stops the container.
68
69The simplest way to start a container from image is ``docker run``. It also pulls the image for you if it is not locally available. For more advanced use, refer to ``docker create``.
70
71Stopped containers are not destroyed, unless you specify ``--rm``. To view all created, running and stopped containers, enter:
72```bash
73$ docker ps -a
74```
75
76Some containers may be designed or configured to be restarted, others are not. Also remember both network ports and volumes of a container are created on start, and not editable later.
77
78### Access a running container
79A running container is accessible using ``docker exec``, or ``docker copy``. You can use ``exec`` to start a root shell in the Shaarli container:
80```bash
81$ docker exec -ti <container-name-or-id> bash
82```
83Note the names and ID's of containers are listed in ``docker ps``. You can even type only one or two letters of the ID, given they are unique.
84
85Access can also be through one or more network ports, or disk volumes. Both are specified on and fixed on ``docker create`` or ``run``.
86
87You can view the console output of the main container process too:
88```bash
89$ docker logs -f <container-name-or-id>
90```
91
92### Docker disk use
93Trying out different images can fill some gigabytes of disk quickly. Besides images, the docker volumes usually take up most disk space.
94
95If you care only about trying out docker and not about what is running or saved, the following commands should help you out quickly if you run low on disk space:
96
97```bash
98$ docker rmi -f $(docker images -aq) # remove or mark all images for disposal
99$ docker volume rm $(docker volume ls -q) # remove all volumes
100```
101
102### Systemd config
103Systemd is the process manager of choice on Debian-based distributions. Once you have a ``docker`` service installed, you can use the following steps to set up Shaarli to run on system start.
104
105```bash
106systemctl enable /etc/systemd/system/docker.shaarli.service
107systemctl start docker.shaarli
108systemctl status docker.*
109journalctl -f # inspect system log if needed
110```
111
112You will need sudo or a root terminal to perform some or all of the steps above. Here are the contents for the service file:
113```

1## Foreword
2
3This guide assumes that:
4
5- Shaarli runs in a Docker container
6- The host's `10080` port is mapped to the container's `80` port
7- Shaarli's Fully Qualified Domain Name (FQDN) is `shaarli.domain.tld`
8- HTTP traffic is redirected to HTTPS

12- [Apache 2.4 documentation](https://httpd.apache.org/docs/2.4/)

14 - [Reverse Proxy Request Headers](https://httpd.apache.org/docs/2.4/mod/mod_proxy.html#x-headers)
15
16The following HTTP headers are set when the `ProxyPass` directive is set:
17
18- `X-Forwarded-For`
19- `X-Forwarded-Host`
20- `X-Forwarded-Server`
21
22The original `SERVER_NAME` can be sent to the proxied host by setting the [`ProxyPreserveHost`](https://httpd.apache.org/docs/2.4/mod/mod_proxy.html#ProxyPreserveHost) directive to `On`.
23

1A brief guide on getting starting using docker is given in [Docker 101](docker-101.md).

4## Get and run a Shaarli image
5
6### DockerHub repository
7The images can be found in the [`shaarli/shaarli`](https://hub.docker.com/r/shaarli/shaarli/)
8repository.
9
10### Available image tags
11- `latest`: latest branch
12- `master`: master branch
13- `stable`: stable branch
14
15The `latest`, `master` and `stable` images rely on:
16
17- [Alpine Linux](https://www.alpinelinux.org/)
18- [PHP7-FPM](http://php-fpm.org/)
19- [Nginx](http://nginx.org/)
20
21Additional Dockerfiles are provided for the `arm32v7` platform, relying on
22[Linuxserver.io Alpine armhf
23images](https://hub.docker.com/r/lsiobase/alpine.armhf/). These images must be
24built using [`docker
25build`](https://docs.docker.com/engine/reference/commandline/build/) on an
26`arm32v7` machine or using an emulator such as
27[qemu](https://resin.io/blog/building-arm-containers-on-any-x86-machine-even-dockerhub/).

52$ docker create -p 8000:80 shaarli/shaarli
53d40b7af693d678958adedfb88f87d6ea0237186c23de5c4102a55a8fcb499101

85```
86
87### Automatic builds
88Docker users can start a personal instance from an
89[autobuild image](https://hub.docker.com/r/shaarli/shaarli/).
90For example to start a temporary Shaarli at ``localhost:8000``, and keep session
91data (config, storage):
92
93```shell
94MY_SHAARLI_VOLUME=$(cd /path/to/shaarli/data/ && pwd -P)
95docker run -ti --rm \
96 -p 8000:80 \
97 -v $MY_SHAARLI_VOLUME:/var/www/shaarli/data \
98 shaarli/shaarli
99```
100
101### Volumes and data persistence
102Data can be persisted by [using volumes](https://docs.docker.com/storage/volumes/).
103Volumes allow to keep your data when renewing and/or updating container images:
104
105```shell
106# Create data volumes
107$ docker volume create shaarli-data
108$ docker volume create shaarli-cache
109
110# Create and start a Shaarli container using these volumes to persist data
111$ docker create \
112 --name shaarli \
113 -v shaarli-cache:/var/www/shaarli/cache \
114 -v shaarli-data:/var/www/shaarli/data \
115 -p 8000:80 \
116 shaarli/shaarli:master
117$ docker start shaarli
118```
