Salt water to Helm Chart's wheel

Flexible way to perform configuration management actions in the Helm chart’s.

We uses years Salt, Chef, Ansible, …​ to do complex configuration steps, but when it came to implement a new feature in Helm Chart app folks once again tend to fall back to bash, curl and the Helm hell templates.


My use-case is simple. I want to update Influxdb chart. and provide way to:

  • create database

  • configure users

  • access right’s

  • continuous_queries

  • retention policies

Quite common stuff when using influxdb. Additionally any lifecycle will need scheduled cron job to prune data etc. which is nothing else then kind of query to the backend.

Common use-case, but what a surprise the Chart did not had these implemented. Not even upstream one. (well google upstream has users + rights but still I was not satisfied.)

Wait, in general these and similar functions we already implemented under "Salt/Chef" tools years ago. miss as well. There must be a huge gap in functions available in what other charts as well.

LEVEL DEVil workshops Running a DevOps workshop for Poland colleagues in March was a one thing but from a day one I was quite sure I will do have to repeat it locally. Practicing DevOps and Continuous Delivery in company as IBM and for the enterprise customers might be a tough task. That’s nothing about enterprises, IBM is actually on a global level doing pretty much well in my eyes in the kind of internal transformation.…

Original website Even though I am now pretty solid in DevOps, applying it on low frequency used blog and keeping django running for years it’s overhead. I will rather spend that one with my kids. Sorry loved #django #python ;-(. On the other hand, during the time, I wrote few pages using static generators and Hugo is the latest one I kept an eye on.…
