Bind consul to a specific IP

[raju-divakaran]

Hello,

Recently we enabled docker-engine on a server where we are having consul agent also running. Soon after starting docker-engine, as we know the docker0 ( default bridge n/w ) is enabled. This results in consul not getting started, as it complains there are multiple internal IPs.

Can we please incorporate a way to bind consul agent to an IP if needed by including that option in the systemd file.

Thanks

Hi @raju-divakaran
You can set any consul configuration option by overriding the attribute, for example in a wrapper recipe:

node.override['consul']['config'][OPT_NAME] = OPT_VALUE

In particular, for bind_addr it will be:

node.override['consul']['config']['bind_addr'] = '10.10.20.30'

Being passed to consul_config resource, these options will be rendered in /etc/consul/consul.json and parsed by the consul daemon after the service restart.

I hope my comment above helps.

Yes, I don't know how I missed that option. Thanks much!
