GCP Set Scopes

September 4, 2020

Here’s how to set the instance scope in GCP. Stop the server.

gcloud compute instances stop server-name

Default scopes.

gcloud beta compute instances set-scopes server-name \
--service-account=your-service-account@gserviceaccount.com \
--scopes=default \
--project your-project-id \
--zone=us-central1-a

Change scopes by adding storage-rw to default.

gcloud alpha compute instances set-scopes servername \
--service-account=your-service-account@gserviceaccount.com \
--scopes=default,storage-rw \
--project your-project-id \
--zone=us-central1-c

Start the server.

gcloud compute instances start server-name

Possible scope values.

default
cloud-platform
storage-rw
and more

Ubuntu and Linux Mint use nano as their default editor. You’ll see it if you try to edit crontab or visudo. Now, there’s nothing wrong with nano, but I prefer using vim instead. Here’s how to change the default editor.

sudo update-alternatives --config editor

You’ll be prompted to change the default editor.

There are 4 choices for the alternative editor (providing /usr/bin/editor).
 
  Selection    Path                Priority   Status
------------------------------------------------------------
  0            /bin/nano            40        auto mode
  1            /bin/ed             -100       manual mode
  2            /bin/nano            40        manual mode
* 3            /usr/bin/vim.basic   30        manual mode
  4            /usr/bin/vim.tiny    15        manual mode
 
Press <enter> to keep the current choice[*], or type selection number:

Type 3 to choose vim basic.

Timedatectl

Here’s another way of setting your server’s timezone. See all the options under North America.

timedatectl list-timezones | grep -i America

Set timezone.

timedatectl set-timezone America/New_York

To check.

date

Restart cron if needed.

systemctl restart cron.service
