ECK: Init container - install-plugins CrashLoopBackoff #55443

rgarcia89 · 2020-04-20T06:04:07Z

Elasticsearch version (bin/elasticsearch --version): 7.6.2

Plugins installed: [repository-azure, repository-s3]

JVM version (java -version):

OS version (uname -a if on a Unix-like system): CentOS 7.7 - Linux 5-21-282-887-1-2338c741 5.6.2-1.el7.elrepo.x86_64 #1 SMP Thu Apr 2 10:55:54 EDT 2020 x86_64 x86_64 x86_64 GNU/Linux

Description of the problem including expected versus actual behavior:
On our DEV Cluster we do have an issue with the init container "install-plugins". It appears when resuming the cluster. As the DEV-Cluster runs in the cloud, we suspend the nodes between 9pm and 6am. Since adding the init container to the ECK deployment, however the elastic pod stuck in Init:CrashLoopBackOff. From the logs I can see the following:

Steps to reproduce:

Please include a minimal but complete recreation of the problem, including
(e.g.) index creation, mappings, settings, query etc. The easier you make for
us to reproduce it, the more likely that somebody will take the time to look at it.

Try to run the init container - install plugins on a pod that already got the plugin installed
Followed the following guide line: https://www.elastic.co/guide/en/cloud-on-k8s/current/k8s-init-containers-plugin-downloads.html

What I would expect:
Maybe it would be better, if the install command checks and if the same version is already installed, and if so ends with a INFO message saying already installed, instead of an error. Otherwise, we need to build a condition that checks if the plugin is already installed before running the install command.

The text was updated successfully, but these errors were encountered:

~~Transfered the issue to https://github.com/elastic/cloud-on-k8s.~~

Edit: transfered it back to the Elasticsearch repo. Sorry for the confusion. I initially misread the first post.
The ask here is to improve the elasticsearch-plugin tool. ECK is just mentioning its usage in this doc.

markharwood · 2020-04-20T08:59:24Z

Maybe we should change the title - the TL/DR on this is to change "install plugins" so it doesn't error if the same plugin version is already installed.

rgarcia89 · 2020-04-20T11:43:07Z

I have create the following workaround for now:

        initContainers:
        - name: install-plugins
          command:
          - sh
          - -c
          - |
            /usr/share/elasticsearch/bin/elasticsearch-plugin list | grep repository-azure
            [[ $? -ne 0 ]] && /usr/share/elasticsearch/bin/elasticsearch-plugin install --batch repository-azure || true
            /usr/share/elasticsearch/bin/elasticsearch-plugin list | grep repository-s3
            [[ $? -ne 0 ]] && /usr/share/elasticsearch/bin/elasticsearch-plugin install --batch repository-s3 || true

rgarcia89 · 2020-04-21T07:03:19Z

What is also strange is the following:
When I delete a pod of the elastic stack the install-plugins initContainer reports differently

This issue looks like a duplicate of ~~55443~~ #61385. [EDIT: pasted the wrong link earlier]

The plan for that issue is to add a flag like --ignore-existing to the elasticsearch-plugin tool so that it could gracefully skip the installation of plugins that already exist. Then, instead of needing to grep the output of elasticsearch-plugin to find out if a plugin needs to be installed, you could just run elasticsearch-plugin install --batch --ignore-existing repository-azure repository-s3, or something to that effect.

I'm going to close this issue in favor of the other one, but please let me know if this is not in fact a duplicate.

an-tex · 2021-01-07T10:23:07Z

It's actually a duplicate of #61385

rgarcia89 · 2021-01-07T13:47:47Z

It's actually a duplicate of #61385

thanks for that, I was about to ask

williamrandolph · 2021-01-07T14:53:31Z

@an-tex Thanks for the correction! That was the link I meant to paste, rather than saying that this issue is a duplicate of itself.
