# Upgrading
|
|
|
|
If your version of Dokku is pre 0.3.0 (check with `dokku version`), we recommend [a fresh install](/docs/getting-started/installation.md) on a new server.
|
|
|
|
## Security Updates
|
|
|
|
For any security related updates, please follow our [Twitter account](https://twitter.com/dokku). As Dokku does not run any daemons, the security risk introduced by our software is minimal.
|
|
|
|
Your operating system may occasionally provide security updates. We recommend setting unattended upgrades for your operating system. Here are some helpful links:
|
|
|
|
- [Arch Linux System Maintenance](https://wiki.archlinux.org/index.php/System_maintenance)
|
|
- [Centos Automatic Security Updates](https://serversforhackers.com/c/automatic-security-updates-centos)
|
|
- [Debian Unattended Upgrades](https://wiki.debian.org/UnattendedUpgrades)
|
|
- [Ubuntu Unattended Upgrades](https://help.ubuntu.com/community/AutomaticSecurityUpdates)
|
|
|
|
Docker releases updates periodically to their engine. We recommend reading their release notes and upgrading accordingly. Please see the [Docker documentation](https://docs.docker.com/) for more details.
|
|
|
|
Finally, we provide a helpful binary called `dokku-update`. This is a recommended package that:
|
|
|
|
- Can be installed separately, so upgrading Dokku will not affect the running of this package.
|
|
- Automates many of the upgrade instructions for you.
|
|
- Provides a clean way for us to further enhance the upgrade process in the future.
|
|
|
|
When installing from source, this is available from `contrib/dokku-update`, and is also available on Debian and RPM-based systems from our package repositories under the name `dokku-update`.

## Upgrade Instructions
|
|
|
|
If Dokku was installed via `apt-get install dokku` or `bootstrap.sh` (most common), upgrade with:
|
|
|
|
```shell
|
|
# update your local apt cache
|
|
sudo apt-get update
|
|
|
|
# stop each running app
|
|
# for 0.11.4 and newer versions, use
|
|
dokku ps:stopall
|
|
# for versions between 0.8.1 and 0.11.3, use
|
|
dokku --quiet apps:list | xargs -L1 dokku ps:stop
|
|
# for versions versions older than 0.8.1, use
|
|
dokku --quiet apps | xargs -L1 dokku ps:stop
|
|
|
|
# update dokku and its dependencies
|
|
sudo apt-get install -qq -y dokku herokuish sshcommand plugn
|
|
|
|
# rebuild all of your applications
|
|
dokku ps:rebuildall # rebuilds all applications
|
|
```
|
|
|
|
> If you have any applications deployed via the `tags` or `tar` commands, do not run the `ps:rebuildall` command,
|
|
> and instead trigger `ps:rebuild` manually for each `git`-deployed application:
|
|
>
|
|
> ```
|
|
> dokku ps:rebuild APP
|
|
> ```
|
|
>
|
|
> Please see the [images documentation](/docs/deployment/methods/images.md) and [tar documentation](/docs/deployment/methods/tar.md)
|
|
> for instructions on rebuilding applications deployed by those plugins.
|
|
|
|
### Upgrade From Source
|
|
|
|
If you installed Dokku from source (less common), upgrade with:
|
|
|
|
```shell
|
|
dokku --quiet apps | xargs -L1 dokku ps:stop # stops each running app
|
|
cd ~/dokku
|
|
git pull --tags origin master
|
|
|
|
# continue to install from source
|
|
sudo DOKKU_BRANCH=master make install
|
|
|
|
# upgrade to debian package-based installation
|
|
sudo make install
|
|
dokku ps:rebuildall # rebuilds all applications
|
|
```
|
|
|
|
To upgrade Herokuish from source, upgrade with:
|
|
|
|
```shell
|
|
cd /tmp
|
|
git clone https://github.com/gliderlabs/herokuish.git
|
|
cd herokuish
|
|
git pull origin master
|
|
IMAGE_NAME=gliderlabs/herokuish BUILD_TAG=latest VERSION=master make -e build-in-docker
|
|
```
