What about error “gcloud command not found”

Sometimes we get an error “gcloud command not found” while using gcloud command. It is mostly because gcloud command is not detected by System. To resolve this error, you need to make sure gcloud command is available in standard Linux directory like /usr/sbin,/usr/sbin etc. If it is installed somewhere else, then you can search that path from below command and set that path in Bash Environment variable. Make sure to run below command as root user.

[root@localhost ~]#find / -name gcloud

How to update components using gcloud update

Sometimes there is a requirement to update google cloud components, in that scenario you need to use gcloud update to update all the required components. Below is the syntax to use that command:-
