问题
I'm new to Heroku. After pushing bad code to the server, I used heroku rollback to revert to a previous version. I then tried to clone this rollback to my computer with:
git clone git@heroku.com:<project>.git <dir>
Unfortunately, this clones the corrupted head, not the rollback. Is there a way to actually clone a specific previous version?
回答1:
When you do rollbacks, the head of your Heroku Git repo will no longer reflect the running state of you app. Check your releases:
$ heroku releases
Rel Change By When
---- ---------------------- ------------------- -------------
v52 Config add AWS_S3_KEY shanley@heroku.com 5 minutes ago
v51 Deploy de63889 kendra@heroku.com 7 minutes ago
v50 Deploy 7c35f77 katie@heroku.com 3 hours ago
The de63889 values are Git commit shas. With those, you can check out that commit locally:
git checkout de63889
