I have come across quite a strange error while attempting to automate a cbbackup across docker containers.

When I try to run cbbackup command from one container to another with couchbase 4.6 I get an error

(u'error: SASL auth socket error: 172.18.0.7:11210, timed out', None)

I have tried every way to figure this out but have not been able to identify the cause. Any help in figuring this out is appreciated.

cbbackup couchbase://192.168.1.5:8091 /tmp/cb/ -u Administrator -p password -b test_bucket -vvv

    I suspect this is something to do with the default docker container network not being able to communicate with the host. If using docker-compose try use the name of the service as the address or run the container using a different network.

  • The solution was either to use the docker container name, or have the docker-compose use network-mode = "host" – Santiago Chiriboga Nov 27 '19 at 20:02
