# Purpose
|
|
|
|
Web UI for overview and management of docker environment.
|
|
|
|
* [Official site](https://www.portainer.io)
|
|
* [Github](https://github.com/portainer/portainer)
|
|
* [DockerHub image used](https://hub.docker.com/r/portainer/portainer/)
|
|
|
|
Portainer is a lightweight management web UI, that allows to easily manage
|
|
docker containers, networks, volumes, images,... the work.
|
|
|
|
In my use it is mostly information tool, rather than a management tool.
|
|
|
|
# Files and directory structure
|
|
|
|
```
|
|
/home/
|
|
└── ~/
|
|
└── docker/
|
|
└── portainer/
|
|
├── portainer-data/
|
|
├── .env
|
|
└── docker-compose.yml
|
|
```
|
|
|
|
* `portainer-data/` - a directory where portainer stores its peristent data
|
|
* `.env` - a file containing environment variables for docker compose
|
|
* `docker-compose.yml` - a docker compose file, telling docker
|
|
how to run the containers
|
|
|
|
You only need to provide the files.</br>
|
|
The directory is created by docker compose on the first run.
|
|
|
|
# docker-compose
|
|
|
|
`docker-compose.yml`
|
|
```yml
|
|

portainer.{$MY_DOMAIN} {

reverse_proxy portainer:9000

|
|
that makes daily snapshot of the entire directory.
|
|
|

|
|
|
|
* down the portainer container `docker-compose down`</br>
