I'm trying to create a script that runs on google container optimized os that calls curl using toolbox but I want to pipe the results to jq by doing something like this:
sudo toolbox curl ... | sudo toolbox jq -r ".something"
but if I do this I get this error message:
Directory tree /var/lib/toolbox/root-gcr.io_google-containers_toolbox-20161110-02 is currently busy.
If I remove toolbox from the pipe (and just pipe to a command like grep that exists in the container) then everything works. But how can I pipe from curl to jq using toolbox?
I solved this by doing:
sudo toolbox bash -c 'curl ... | jq -r ".something"'
