## Automatic update
|
|
|
|
An update script in your mailcow-dockerized directory will take care of updates.
|
|
|
|
But use it with caution! If you think you made a lot of changes to the mailcow code, you should use the manual update guide below.
|
|
|
|
Run the update script:
|
|
```
|
|
./update.sh
|
|
```
|
|
|
|
If it needs to, it will ask you how you wish to proceed.
|
|
Merge errors will be reported.
|
|
Some minor conflicts will be auto-corrected (in favour for the mailcow: dockerized repository code).
|
|
|
|
### Options
|
|
|
|
```
|
|
# Options can be combined
|
|
|
|
# - Check for updates and show changes
|
|
./update.sh --check
|
|
|
|
# Do not try to update docker-compose, **make sure to use the latest docker-compose available**
|
|
./update.sh --no-update-compose
|
|
|
|
# - Do not start mailcow after applying an update
|
|
./update.sh --skip-start
|
|
|
|
# - Force update (unattended, but unsupported, use at own risk)
|
|
./update.sh --force
|
|
|
|
# - Run garbage collector to cleanup old image tags and exit
|
|
./update.sh --gc
|
|
|
|
# - Update with merge strategy option "ours" instead of "theirs"
|
|
# This will **solve conflicts** when merging in favor for your local changes and should be avoided. Local changes will always be kept, unless we changed file XY, too.
|
|
./update.sh --ours
|
|
|
|
# - Don't update, but prefetch images and exit
|
|
./update.sh --prefetch
|
|
```
|
|
|
|
### I forgot what I changed before running update.sh
|
|
|
|
See `git log --pretty=oneline | grep -i "before update"`, you will have an output similar to this:
|
|
|
|
```
|
|
22cd00b5e28893ef9ddef3c2b5436453cc5223ab Before update on 2020-09-28_19_25_45
|
|
dacd4fb9b51e9e1c8a37d84485b92ffaf6c59353 Before update on 2020-08-07_13_31_31
|
|
```
|
|
|
|
Run `git diff 22cd00b5e28893ef9ddef3c2b5436453cc5223ab` to see what changed.
|
|
|
|
### Can I role back?
|
|
|
|
Yes.
|
|
|
|
See the topic above, instead of a diff, you run checkout:
|
|
|
|
```
|
|
docker-compose down
|
|
# Replace commit ID 22cd00b5e28893ef9ddef3c2b5436453cc5223ab by your ID
|
|
git checkout 22cd00b5e28893ef9ddef3c2b5436453cc5223ab
|
|
docker-compose pull
|
|
docker-compose up -d
|
|
```
|
|
|
|
