$ ./scripts/upgrade-from-mattermost-docker.sh

```
|
||||
|
||||
Environment variables for upgrading:
|
||||
`ttf` means, the script 'tries to find' the environment variables.

You can overwrite any of these variables before running this script with:
|

```
|

$ export VAR_NAME_FROM_ABOVE=yourValue
|
||||
$ export PATH_TO_MATTERMOST_DOCKER=path/to/mattermost-docker
|
