Bug: weird issue with work directory path

[mjf]

stacker version

v0.40.1-e54a685 liblxc a330126b45c7c3b6fcf0f9ba6c1eda7bdb4e508a

Describe the bug

For example

$ pwd
/home/user/tmp/2023-01-19-stacker-test-13:13:06

Then create the sample hello.stacker.yaml and the hello_stacker.go files from the docs in the directory and continue with the example from the docs...

$ stacker build -f hello.stacker.yaml
preparing image build-hello-stacker...
copying /home/user/tmp/2023-01-19-stacker-test-13:13:06/hello_stacker.go
loading docker://zothub.io/c3/ubuntu/go-devel-amd64:1.19.2
error: couldn't import base layer go-devel-amd64: Invalid image 13:06/.stacker/layer-bases/oci:go-devel-amd64
error: exit status 1

👎

To reproduce

1. Configuration - none
2. Client tool used - the stacker utility only
3. Seen error - see above

Expected behavior

Work directory path doesn't mess up stacker execution.

@mjf pls. get the latest stacker like so ^
Also pls share your stacker file so we can try to reproduce the error.

[smoser]

The problem here is just the ':' in the path (as I think @mjf suspected).

Stacker uses 'oci' repository on disk. The error then is when stacker tries to copy "docker://zothub.io/c3/ubuntu/go-devel-amd64:1.19.2" to local disk (or maybe copying it out). In an "oci url", the format is ":" delimited.

 oci:<path>:tag

And in this case, ':" occurs in the path, so that is confusing things.
I'm not sure if there is an easy path out (involving correctly escaping or quoting) or not.
