Pulsar: Error at starting apachepulsar/pulsar-dashboard docker container within Kubernetes

[julio666]

Hi there!

Issue
I've used the helm chart available in the 2.4.2 Apache Pulsar project. Every pod is created and running correctly except pulsar-dashboard which has the CrashLoopBackOff status.

It looks like the initdb file from postgresql does not exist. Here what the logs are saying :

Starting Pulsar dasboard
+ /pulsar/init-postgres.sh
+ rm -rf '/data/*'
+ chown -R postgres: /data
+ chmod 700 /data
+ sudo -u postgres /usr/lib/postgresql/9.6/bin/initdb /data/
sudo: /usr/lib/postgresql/9.6/bin/initdb: command not found

To Reproduce
Simply install the helm chart with values-mini.yaml and look at the pods in the pulsar namespace. To be sure, I've tried to run the container alone on my machine and I get the same error.

Expected behavior
I would expect Pulsar Dashboard to run properly :)

Cluster Kubernetes:

• Server version 1.12 on linux/amd64 platform

It looks like the installed version of postgresql is now 11 and no more 9.6.

running into same problem too.
use “kubectl set image deployment”
set image to
pulsar-dashboard:2.3.0
is ok.

then I have another problem:

Thanks @julio666 , Seems you already found the version issue . Would you like to provide a PR to fix it?

[jiazhai]

And also in master pulsar-manager is added in helm, you could try pulsar-manager instead of dashboard.

I'm looking for a working docker-compose for local standalone pulsar with dashboard, someone already made it?

[julio666]

@jiazhai no problem, I'll do it. Thanks for the tip about pulsar-manager.

there is a bug in apachepulsar/pulsar-dashboard:2.4.2 docker image,
/usr/lib/postgresql/9.6/bin/initdb - > /usr/lib/postgresql/11/bin/initdb for /pulsar/init-postgres.sh
perhaps you can set image tag to other version, apachepulsar/pulsar-dashboard:2.4.1 works fine for me.

Same issue here, downgraded to 2.4.1 and now it's up and running!

[Javac7]

I made a build from version 2.4.2 so you can pull here: docker pull javac7/apachepulsar-dashboard
or can get the docker-compose here: pulsar compose.

[jiazhai]

@tuteng also has already pushed the 2.4.2 version into apachepulsar 's dockerhub, @julio666 Could we close this issue?

[julio666]

@jiazhai yes, I close it !

Running into this issue with the image apachepulsar/pulsar-dashboard:2.5.1 and the following error:

Starting Pulsar dasboard
+ /pulsar/init-postgres.sh
+ rm -rf '/data/*'
+ chown -R postgres: /data
+ chmod 700 /data
+ sudo -u postgres /usr/lib/postgresql/11/bin/initdb /data/
sudo: /usr/lib/postgresql/11/bin/initdb: command not found

Inspecting the docker image, it appears /usr/lib/postgresql/9.6/bin/initdb exists but /usr/lib/postgresql/11/bin/initdb does not.

You can try http://pulsar.apache.org/docs/en/administration-pulsar-manager/ first. https://github.com/apache/pulsar-manager is a better management tool. Let's take a look at this problem next. @complex64

Thanks for the pointer to the manager, we'll give that project a try :+1:
