Growing /tmp directory #564

Open Anumrati opened 3 months ago

Anumrati commented 3 months ago

What happened?

When trying to upgrade the operator from v1.13.0 to v1.15.0 we started having problems with the growing /tmp directory. In the earlier version of the operator, directories from /tmp/pulumi-working/pulumi-kubernetes-operator/ were deleted after reconciliation. After change in PR-490 the .pulumi directory, which weighs about 800 MB in our instance, remains in each stack. With about 200 stacks we have, we need over 100 GB of extra space, which is not the best option.

Thanks for filing this issue @Anumrati; it looks like we need a way to either separate the credentials configuration from the pulumi home dir (https://github.com/pulumi/pulumi/issues/13919) as an alternate solution for #483 or support some sort of reuse/hardlinking of the pulumi binaries when using multiple pulumi home dirs.
