Remote hosts

[PrzemekSkw]

Hello, it's possible to add remote hosts from Tailscale network? Do I have to install WUD on every host? Regards.

Hi,

I personally don't know Tailscale network but wud can connect to multiple Docker hosts using TCP.

https://fmartinou.github.io/whats-up-docker/#/configuration/watchers/?id=variables

So if the remote hosts are reachable via TCP, it should work.

Hi, thanks for answer. Can You help me how to add another host?

[PrzemekSkw]

Hi @fmartinou I add variable in Portainer like that:

I still see only my local host containers. But see my remote hosts in Watchers section:

Can You tell me what is wrong?

[fmartinou]

Hi @PrzemekSkw ,

For the remote host to watch, you cannot use the socket configuration, which is by design intended for local use.

You need to:

1. Expose the Docker API over TCP (a tuto here)
2. Configure WUD to connect to the API using TCP (Basic example here)

Following on this as I'm having the same use case, trying to connect different machines through tailscale and docker socket proxy. I see on their github that dsp runs with a lot of stuff secured by default, which would stop wud from doing it's job. https://github.com/Tecnativa/docker-socket-proxy#grant-or-revoke-access-to-certain-api-sections there's the list of stuff you can configure, what should I change in order for wud to work??

Really would love to make this one work. Thank you!

i'd like to second the request for a list of permissions required for a socket proxy

Adding the IMAGES permission to my proxy (in addition to the already enabled CONTAINERS) allows WUD to startup and monitor. Presumably you'd need more permissions to enable triggers to actually pull new images/recreate containers
