Tar Path Format Issue

Posted on | Edited on | In

I haven’t noticed the path format when I created tarball, this time the format issue plays as a major blocker.

We use a module tar file to deploy Zen in ICP4D cluster, when I use my customized tar file, I get:

Starting the installation ...
There was a problem installing /xxx/InstallPackage/modules/xxx-iisee-zen:1.0.0/charts/updated_xxx-iisee-zen100.tgz chart. Reason: chart metadata (Chart.yaml) missing

Let’s highlight the command:

1
Running command: /xxx/InstallPackage/components/dpctl --config /xxx/InstallPackage/components/install.yaml helm rewriteChart -i /xxx/InstallPackage/modules/./xxx-iisee-zen:1.0.0//charts/*.tgz -o /xxx/InstallPackage/modules/./xxx-iisee-zen:1.0.0//charts/updated_xxx-iisee-zen100.tgz

Look carefully there is a ./ in path /xxx/InstallPackage/modules/./xxx-iisee-zen:1.0.0/...., this is because I create tarball use:

1
tar cf xxx-iisee-zen-1.0.0.tar ./xxx-iisee-zen:1.0.0

the ./ will be put in the extract path! which is the trouble maker.

Correct way:

1
2
cd <xxx-iisee-zen:1.0.0 parent folder>
tar cf xxx-iisee-zen-1.0.0.tar xxx-iisee-zen:1.0.0

If we list the tarball contents, no prefix in the file structure:

1

tar tvf xxx-iisee-zen-1.0.0.tar
