kafka-connect not starting on docker Swarm #110

Open jpchev opened 2 years ago

jpchev commented 2 years ago

I'm using the attached docker compose file kafka.zip, and these commands

docker swarm init docker stack deploy --prune --with-registry-auth -c kafka.yml kafka_pd

then the following commands shows 0/1 replicas deployed

[centos@test ~]$ sudo docker service ls
ID             NAME                          MODE         REPLICAS   IMAGE                                  PORTS

jqu6slwmc8nh   kafka_pd_kafka-connect   replicated   0/1        confluentinc/cp-kafka-connect:latest   *:8083->8083/tcp
4o1yo6y802d8   kafka_pd_zookeeper       replicated   1/1        confluentinc/cp-zookeeper:latest

do you have an idea why the kafka-connect service is not being deployed correctly?

it is necessary to add the 'hostname' property in the service configuration file. Because the swarm network uses DNS in the container name by default.
