Debian: Cannot connect to docker daemon #63

Open vdo opened 3 years ago

vdo commented 3 years ago

I just deployed 3 nodes on a cloud platform, using debian 10, and I followed the tutorial to connect all of them.

Everything worked fine, but when I try to run overnode ps or overnode up, it fails to connect to the docker daemons, with the output:

root@on2:~# overnode ps
[1] Couldn't connect to Docker daemon at http://10.39.240.1:2375 - is it running?
[1] 
[1] If it's at a non-standard location, specify the URL with the DOCKER_HOST environment variable.
[3] Couldn't connect to Docker daemon at http://10.39.240.3:2375 - is it running?
[3] 
[3] If it's at a non-standard location, specify the URL with the DOCKER_HOST environment variable.
[2] Couldn't connect to Docker daemon at http://10.39.240.2:2375 - is it running?
[2] 
[2] If it's at a non-standard location, specify the URL with the DOCKER_HOST environment variable.

Maybe I missed some step, but I reviewed the docs and I cannot find any.

Some info:

After redeploying the stack with Ubuntu 18.04, looks like is a problem specific to Debian 10

Hi. Thanks for reporting. Looks like it is weave issue, but nothing suggests in the logs what might be wrong... Do you have docker ps status captured before running overnode up command?

jtagcat commented 3 years ago

I was planning to replicate the issue today, going to sleep atm.

I'll try tomorrow or the day after.

e: I can replicate; haven't debugged much so far

The output was basically the same, I could not connect to the Docker daemon
