Subject: [pve-devel] [PATCH container] config: allow empty environment variables
Date: Mon, 17 Nov 2025 13:49:03 +0100 [thread overview]
Message-ID: <20251117124935.126982-1-f.schauer@proxmox.com> (raw)
This fixes a problem with the docker.io/httpd OCI image which specifies
an empty environment variable. This violated the pattern of the `env`
property, causing `pct config <vmid>` to fail with:
```
env: value does not match the regex pattern
```
