The previous indent(6, containerd_config_update_command) attempt didn't
fix the YAML parse error — the heredoc in stacks/infra/main.tf has
mixed indentation (most lines at col 2, inner shell heredoc bodies
like CONTAINERD_GC and KUBELET_PATCH at col 0). Any uniform-prefix
function (indent / replace / join) preserves the relative offset, so
the column-0 lines always end up below the block's first-line indent
and YAML terminates the literal block early.
The cleanest fix is a refactor: move the containerd setup snippet out
of the inline heredoc into a cloud-init `write_files` block (script
file delivered to the VM, then `bash /path/to/script.sh` in runcmd).
That bypasses the multi-line YAML interpolation entirely.
Reverting to the previous (also-broken) interpolation pattern with a
big WARNING comment instead. New k8s nodes still need manual backfill
after first boot — node4 was backfilled today; see memory id=2767/2772
for the backfill steps. Tracked separately.
