Setting up Camunda Platform 8 Self-managed solution using docker

Camunda 8 Topics Discussion & Questions
1

I’m using the docker-compose from here to set up my camunda engine locally on Ubuntu 22.04. I’m using the docker-compose-core.yaml for minimal setup without Identity, Keycloak and Optimize.

Zeebe and ElasticSearch containers are starting up properly. But Operate and Tasklist are not.

Tasklist Log:

I’m fairly new to both Camunda and Docker. Any help would be appreciated. Thanks!

Hi @Maheshkumar_Sundaram

I have just tried the following Docker compose camunda-platform/docker-compose-core.yaml at main · camunda/camunda-platform · GitHub (the latest 8.0.4 version) on a Windows PC. That works.

Are you sure Elasticsearch is actually started? It does take some minutes to start…

Yeah. I waited and checked the status of the containers using docker ps -a command and verified that it’s up and healthy.

Hi @Maheshkumar_Sundaram

How about if you try restarting the Tasklist and Operate services, using docker-compose restart <servicename>?

Josh

6

Tried restarting. The problem persists. Same log.

7

I checked out the repo on my Macbook, and ran:

docker-compose -f docker-compose-core.yaml up

I saw the refused connection messages, but then ES came up and Tasklist and Operate started.

What about doing docker-compose -f docker-compose-core.yaml down then docker-compose -f docker-compose-core.yaml up?

Maybe pulling the ES container made it take too long?

Josh

8

Yeah. That’s why I waited for ES to start. Once it was up and healthy, I tried restarting Operate and Tasklist. But again they are not able to connect to ES :unamused:

9

What about this: try getting a shell in one of the containers to see if it can see the ES container.

I start the stack, then do docker ps -a to get the Tasklist container Id.

Then:

docker exec -it <Tasklist_Container_Id> bash
apt update
apt install iputils-ping
ping elasticsearch

PING elasticsearch (172.20.0.2) 56(84) bytes of data.
64 bytes from elasticsearch.camunda-platform_camunda-platform (172.20.0.2): icmp_seq=1 ttl=64 time=0.079 ms

Also, are there any errors in the ES container log?

Thank you so much for trying to help solve issue.

I resolved the issue by performing a clean install of Docker and now it’s working.
I believe it’s something to do with DNS resolving issue.
