N8n can't start in kubernetes

Jeronimo_Jose_Diaz_G · November 22, 2024, 2:42pm

Describe the problem/error/question

I am trying to deploy n8n to kubernetes using GitHub - 8gears/n8n-helm-chart at 0.25.2 helm chart but I cannot get it up and running, I have defined below values.

I guess I am missing some config but I cannot get to it.

N8N_LOG_LEVEL: "debug"
    N8N_METRICS: "true"
    DB_TYPE: sqlite
    DB_SQLITE_VACUUM_ON_STARTUP: true
    N8N_EDITOR_BASE_URL: https://xxxxxxxx/
    N8N_HOST: https://xxxxxxx/
    DB_LOGGING_ENABLED: query
    N8N_COMMUNITY_PACKAGES_ENABLED: false

What is the error message (if any)?

hello @Jeronimo_Jose_Diaz_G

At least, N8N_HOST variable should be an FQDN, not the url

Jeronimo_Jose_Diaz_G · November 25, 2024, 8:00am

Hello,

Thanks so much for the answer. Unfortunately, after removing the protocol and final slash from N8N_HOST environment variable, I still get below error which looks very similar to the one I was getting before updating the environment variable.

The main problem I have is I don’t understand what the error could be from the logs

barn4k · November 25, 2024, 3:05pm

I only can see there is improper value for the variable DB_LOGGING_ENABLED. It should be set as boolean (true / false)

Jeronimo_Jose_Diaz_G · November 26, 2024, 7:02am

Thanks @barn4k for your response.

I have updated the value of that variable and, unfortunately, n8n does not want to start yet. These are the logs

Log level is set to debug but I am still missing more information in the logs. Is there a way to get more info to know what is going on? Any hint to try to get it up and running?

How are you starting it? seems it starts and right after it receives an exit signal…

I am using helm chart to deploy it GitHub - 8gears/n8n-helm-chart: A Kubernetes Helm chart for n8n - a workflow automation tool. Easily automate tasks across different services on self hosted onKubernetes

What it basically does is to deploy a pod (container) in kubernetes to run n8n. The definition of the pod that is being deployed into kubernetes is below

I think 128Mb is too low for n8n to operate. Try with 512

Jeronimo_Jose_Diaz_G · November 27, 2024, 12:48pm

@barn4k That was the issue. Too low resources assigned to the pod. Thanks so much for all your help.

Kind regards
