No downtime documentation is not compatible with most Ubuntu installations
Hi,
The "no downtime" Omnibus documentation uses the following command to trigger the reconfigure action without post-deployment migration:
SKIP_POST_DEPLOYMENT_MIGRATIONS=true sudo gitlab-ctl reconfigure
But for a default Ubuntu installation, sudoers cannot inject env variables to sudo commands, and the SKIP_POST_DEPLOYMENT_MIGRATIONS
variable will not pass through the sudo.
# Does not work
$ foo=bar sudo env | grep foo
<nothing>
# Works
$ sudo foo=bar env | grep foo
foo=bar
Without further configuration consideration, the following command should work (with default configurations), by injecting the variable in the sudo
command:
sudo SKIP_POST_DEPLOYMENT_MIGRATIONS=true gitlab-ctl reconfigure
This injection could be prevented by a sudoers configuration with a !SETENV
.
