## Setup Docker EasyHAProxy
|
|
|
|
This method involves using a standalone Docker installation to discover containers
|
|
and configure HAProxy.
|
|
|
|
EasyHAProxy inspects Docker containers and retrieves labels to configure HAProxy.
|
|
Once it identifies a container with at least the label 'easyhaproxy.http.host,'
|
|
it configures HAProxy to redirect traffic to that container.
|
|
To accomplish this, EasyHAProxy may need to attach the same network to its container.
|
|
|
|
It's recommended to create a network external to EasyHAProxy, although it's not mandatory.
|
|
|
|
:::warning Limitations
|
|
- You cannot mix Docker containers with Swarm containers.
|
|
- This method does not work with containers that use the `--network=host` option. See [limitations](limitations.md) for details.
|
|
:::
|
|
|
|
For example:
|
|
|
|
```bash title="Create EasyHAProxy network"
|
|
docker network create easyhaproxy
|
|
```
|
|
|
|
And then run the EasyHAProxy:
|
|
|
|
```bash title="Run EasyHAProxy container"
|
|
docker run -d \
|
|
--name easy-haproxy-container \
|
|
-v /var/run/docker.sock:/var/run/docker.sock \
|
|
-e EASYHAPROXY_DISCOVER="docker" \
|
|
# + Environment Variables \
|
|
-p 80:80 \
|
|
-p 443:443 \
|
|
-p 1936:1936 \
|
|
--network easyhaproxy
|
|
byjg/easy-haproxy
|
|
```
|
|
|
|
Mapping to `/var/run/docker.sock` is necessary to discover the docker containers and get the labels;
|
|
|
|
## Running containers
|
|
|
|
To make your containers "discoverable" by EasyHAProxy, this is the minimum configuration you need:
|
|
|
|
```bash title="Run container with EasyHAProxy labels"
|
|
docker run -d \
|
|
--label easyhaproxy.http.host=example.org \
|
|
--label easyhaproxy.http.port=80 \
|
|
--label easyhaproxy.http.localport=8080 \
|
|
--network easyhaproxy
|
|
my/image:tag
|
|
```
|
|
|
|
Once the container is running, EasyHAProxy will detect automatically and start to redirect all traffic from `example.org:80` to your container.
|
|
|
|
You don't need to expose any port in your container.
|
|
|
|
Please follow the [docker label configuration](container-labels.md) to see other configurations available.
|
|
|
|
## Setup the EasyHAProxy container
|
|
|
|
You can configure the behavior of the EasyHAProxy by setup specific environment variables. To get a list of the variables, please follow the [environment variable guide](environment-variable.md)
|
|
|
|
## Setup certificates with ACME (e.g. Letsencrypt)
|
|
|
|
Follow [this link](acme.md)
|
|
|
|
## Setup your own certificates
|
|
|
|
Follow [this link](ssl.md)
