====== HA-Proxy on RouterOS7 ======
===== prerequisites =====
you need:\\
[[installatie_handleidingen:mikrotik:usb-disk|an external disk on the USB port]]\\
[[installatie_handleidingen:mikrotik:containers-plugin| the containers plugin on RouterOS7]]\\

===== network connections =====
There are several ways to connect the HA-Proxy container to the network, here we chose to give it its own IP.\\
follow the instructions to create a [[installatie_handleidingen:mikrotik:virtual-container-network|virtual network interface]] with IP and connection to the desired VLAN.

===== Persistent volumes location =====
For the persistent volume of the container we create a directory
<code>
/file 
add type=directory name=/usb1/persistent-volumes/haproxy/config-dir

</code>

===== configuration file =====
Start by creating the config file on your workstation, ''vi haproxy.cfg'', add the following content for a test to the website at 10.100.10.103

<code>
global
    daemon
    maxconn 256

defaults
    mode http
    timeout connect 5s
    timeout client  50s
    timeout server  50s

frontend http_in
    bind *:80
    default_backend web_servers

backend web_servers
    balance roundrobin
    server srv1 10.100.10.103:80 check
</code>

upload this config file to the preveously crated location.
<code>
scp haproxy.cfg styx:/usb1/persistent-volumes/haproxy/config-dir
</code>

===== set container mount =====
Now set the volume with the config file as a persistent volume mount in the container:
<code>
/container/mounts
add name=HAPROXY_CONF dst=/usr/local/etc/haproxy src=/usb1/persistent-volumes/haproxy/config-dir
</code>

===== deploy the container =====
<code>
/container
add remote-image=library/haproxy:latest interface=veth-haproxy root-dir=usb1/persistent-volumes/haproxy/root-dir mounts=HAPROXY_CONF name=haproxy
</code>

zoek het nummer van de containerdefinitie op: ''/container/print''
en start dat nummer (in ons geval 0)
<code>
/container
start number=0
</code>
