hero: A recipe for a sexy view of your Docker Swarm
|
|
|
|
# Portainer
|
|
|
|
[Portainer](https://portainer.io/) is a lightweight sexy UI for visualizing your docker environment. It also happens to integrate well with Docker Swarm clusters, which makes it a great fit for our stack.
|
|
|
|
|
|
|
|
This is a "lightweight" recipe, because Portainer is so "lightweight". But it **is** shiny...
|
|
|
|
## Ingredients
|
|
|
|
1. [Docker swarm cluster](/ha-docker-swarm/design/) with [persistent shared storage](/ha-docker-swarm/shared-storage-ceph.md)
|
|
2. [Traefik](/ha-docker-swarm/traefik) configured per design
|
|
3. DNS entry for the hostname you intend to use, pointed to your [keepalived](ha-docker-swarm/keepalived/) IP
|
|
|
|
## Preparation
|
|
|
|
### Setup data locations
|
|
|
|
Create a folder to store portainer's persistent data:
|
|
|
|
```
|
|
mkdir /var/data/portainer
|
|
```
|
|
|
|
### Setup Docker Swarm
|
|
|
|
Create a docker swarm config file in docker-compose syntax (v3), something like this:
|
|
|

I share (_with my [patreon patrons](https://www.patreon.com/funkypenguin)_) a private "_premix_" git repository, which includes necessary docker-compose and env files for all published recipes. This means that patrons can launch any recipe with just a ```git pull``` and a ```docker stack deploy``` 👍

```

|
version: "3"

services:
|
|
app:

|
image: portainer/portainer

|
|
- /var/data/portainer:/data

|
|

|
|
- traefik.port=9000
|
|
placement:
|
|
constraints: [node.role == manager]
|
|
command: -H unix:///var/run/docker.sock
|
|
|
|
networks:
|
|
traefik_public:
|
|
external: true
|
|
```
|
|
|
|
## Serving
|
|
|
|
### Launch Portainer stack
|
|
|
|
Launch the Portainer stack by running ```docker stack deploy portainer -c <path -to-docker-compose.yml>```
|
|
|
|
Log into your new instance at https://**YOUR-FQDN**. You'll be prompted to set your admin user/password.
|
|
|
|
## Chef's Notes
|
|
|
|
1. I wanted to use oauth2_proxy to provide an additional layer of security for Portainer, but the proxy seems to break the authentication mechanism, effectively making the stack **so** secure, that it can't be logged into!
