Failed to initialize plugins

[shanelanan]

Summary

When running tflint --recursive , I am unable to initialize the plugins.

What I tried:
Install as as root user and call tflint --init as root
Install as root and call tflint --init, then switch to jenkins user and call tflint --init again.

Both --init calls work fine, the plugins are there. However, when I switch to jenkins user to run my pipeline, I get the error message about failed to initialize.

Any guidance about which permissions to open up to fix this would be much appreciated. I already have the /usr/local/bin/tflint on permissions 777.

Command

tflint --recursive --force

I solved it. The socket needs to write to a temp directory. Make sure your temp directory has the proper permissions. My build process and jenkins agent did not.
