Customize broken since luarocks-admin not on path

[morvaiff]

customize/Dockerfile cannot be used to build custom Kong images with additional bundled plugins from a curated list, since packer.lua invokes luarocks-admin in a shell, but the tool is not available on the system path.

The command '/bin/sh -c /usr/local/openresty/luajit/bin/luajit /packer.lua -- "$INJECTED_PLUGINS"' returned a non-zero code: 1

I see this was addressed in 9cc3ca4 and faf4f06, but then removed in 9d58e41, together with some test cases.

Shouldn't the luarocks-admin symbolic link in /usr/local/bin be included after all (either as in the above commits, or in the build stage of customize/Dockerfile)? Or does the removal of tests indicate that creating custom images this way is no longer supported?

Good evening, I encountered the same issue while trying to create a custom Kong image with the kong-oidc plugin. The Kong version is 3.8 (latest). Has anyone managed to resolve this and could provide guidance on building the images? Thank you very much, looking forward to your response.

Solved... I had "simply" cloned the git repository... downloading the zip works!!!!! this is obviously absurd... at least to me. Tragic experience... we didn't start off well...

This was fixed a while ago: Kong/kong#13372

If you accidentally run into it here's a one-liner that should fix it:

sed 's#/bin/luarocks'\''#/bin/luarocks-admin'\''#' /usr/local/bin/luarocks > /usr/local/bin/luarocks-admin && chmod +x /usr/local/bin/luarocks-admin

It takes the luarocks wrapper script, copies it to luarocks-admin and replaces all occurrences of luarocks to luarocks-admin
