How to rename a chroot¶
In the openEuler copr instance, we unfortunately need to rename a chroot.
The operations need to be done can be described as:
[backend]: symlinks all the old chroot dir in resultdir to the new one
[frontend]: change the os_release/os_version in frontend table mock_chroot
[builder]: add new mock chroot configs to all builder
After these operations are complete, a new chroot will be displayed at all frontend pages, and all the old repo config files should be still usable.
To be more precisely, here are some operation details:
Suppose you have a chroot named
foo-bar-x86_64 and want to rename it to
Login as copr user to backend node, and run:
$ /usr/bin/copr-rename-chroot --real-run --pair foo-bar-x86_64:new-foo_bar-x86_64
/usr/bin/copr-rename-chroot script will rename the dir in
You may note the
--real-run arguement, without it the script will perform a dry-run and just print the operations out.
Run the command without
real-run until you make sure all the operations are expected!
Login to the frontend database and run:
coprdb# UPDATE mock_chroot SET os_version='foo_bar', os_release='new' WHERE os_version='foo' AND os_release='bar' AND arch='x86_64'
Explain: the SQL will rename the old chroot which name is
new-foo_bar-x86_64 in database, this operation will make webUI&copr-cli see the new chroot.
Update your mock package to ensure the
