Unable to join server once I init the node with hostname in Docker env

Li_Liu · September 26, 2019, 5:31pm

I have a Linux Ubuntu 18 machine. with Docker installer. Couchbase version is couchbase:community-5.0.1
Plan to initial a cluster with 3 couchbase nodes. I have listed the reproduce steps here:

github.com

liulirun/couchbase-multinodes/blob/master/reproduce-steps

#initial couchbase containers
docker run -d --name devbox_couchbase1 --hostname couchbase1.dev.example.com couchbase:community-5.0.1 
docker run -d --name devbox_couchbase2 --hostname couchbase2.dev.example.com couchbase:community-5.0.1 
docker run -d --name devbox_couchbase3 -p 8091-8094:8091-8094 -p 11210:11210 --hostname couchbase3.dev.example.com couchbase:community-5.0.1 

#initial node with hostname
docker exec `docker inspect --format '{{ .Id }}' devbox_couchbase1` bash -c 'couchbase-cli node-init -c localhost -u ops -p ops --node-init-hostname couchbase1.dev.example.com'
docker exec `docker inspect --format '{{ .Id }}' devbox_couchbase1` bash -c 'curl -s -X POST -u ops:ops http://127.0.0.1:8091/node/controller/rename -d hostname=couchbase1.dev.example.com'

docker exec `docker inspect --format '{{ .Id }}' devbox_couchbase2` bash -c 'couchbase-cli node-init -c localhost -u ops -p ops --node-init-hostname couchbase2.dev.example.com'
docker exec `docker inspect --format '{{ .Id }}' devbox_couchbase2` bash -c 'curl -s -X POST -u ops:ops http://127.0.0.1:8091/node/controller/rename -d hostname=couchbase2.dev.example.com'

docker exec -it $(docker ps -q -f name=devbox_couchbase3) couchbase-cli cluster-init --cluster-username ops --cluster-password ops --cluster-port 8091 --cluster-ramsize 512 --cluster-name couchbase.dev.example.com --services data,index,query,fts
docker exec `docker inspect --format '{{ .Id }}' devbox_couchbase3` bash -c 'curl -s -X POST -u ops:ops http://127.0.0.1:8091/node/controller/rename -d hostname=couchbase.dev.example.com'

due to this forum do not let me insert more than 2 links

After this is done, I logged into localhost/8091 using ops/ops credentials.
There is a default node existing already

When I try to add a server using couchbase1.dev.example.com, I got
Attention: Prepare join failed. Joining node to itself is not allowed.
If I try to add a server using IP of couchbase1.dev.example.com ( 172.17.0.2) , I got error:
Attention: Join completion call failed. Got HTTP status 500 from REST call post to 172.17.0.2:8091-completeJoin. Body was: “[“Unexpected server error, request logged.”]”

To compare with this, if I do not rename the node with hostname, then I will can join the node with cluster without any problem. follow the doc in couchbase docs ( docker-deploy-multi-node-cluster)

Can some one point me some directions how I could fix this? Much appreciated.
