[HAProxy][1] is a free, open source high availability solution, providing load
|
||
|
|
balancing and proxying for TCP and HTTP-based applications by spreading
|
||
|
|
requests across multiple servers.
|
||
|
|
|
||
|
|
## docker-compose.yml
|
||
|
|
|
||
|
|
```yaml
|
||
|
|
haproxy:
|
||
|
|
image: haproxy:alpine
|
||
|
|
volumes:
|
||
|
|
- ./haproxy.cfg:/usr/local/etc/haproxy/haproxy.cfg
|
||
|
|
net: host
|
||
|
|
restart: always
|
||
|
|
```
|
||
|
|
|
||
|

## haproxy.cfg
