Cant start any consul cluster

[longtechmaster]

I can start all examples/ at local but not working in my server (a Virtual Machine), consul can't join with other

I tried to run all command in docker-alpine/alpine-consul/root/usr/bin/ in consul-container

dig +short ${1:-$CONSUL_SERVER_NAME} in container-find file not working, that make script consul-join, consul-available cant run (and in this container, i cant ping to any website. )

Yeah, I've had dig not work before. Usually host or getent or something similar will. You should find something that works and replace that script with that works in your containers on the VM. Then, everything should be fine.

Also, have you considered moving to Kubernetes? There is no need for Consul in Kubernetes.

tks you! I run docker-compose first and run a script after that. The script show list ip of consul from the container outside ( base on docker-inspect) and export to text file. The text file is used to volumes from outside to /root/usr/bin/ inside container. I changed container-find file -> read the text file.

This my way. I cant show list ip from inside container with dig, getent, host, ... at my server (Debian Virtual Machine).

Can you help me another better way! Tks you!

when i changed dig to getent ahosts ${1:-$CONSUL_SERVER_NAME} | awk '{print $1}' | awk 'NR % 2' at local

i receive list ip same dig

/ # getent ahosts ${1:-$CONSUL_SERVER_NAME} | awk '{print $1}' | awk 'NR % 2'
172.18.0.9
172.18.0.8
172.18.0.5
/ # dig +short ${1:-$CONSUL_SERVER_NAME}
172.18.0.8
172.18.0.9
172.18.0.5
/ #

Are you familiar with how Consul works?

You could try setting CONSUL_BOOTSTRAP_DEBUG to true and then review the log file at /var/log/consul-bootstrap/consul-bootstrap.log. This documents decisions made by the custom Consul bootstrapping functionality within these containers.

Also, have a read of https://github.com/smebberson/docker-alpine#consul-and-service-discovery and review the example. See if you can get that to work.
