If your version of Dokku is pre 0.3.0 (check with dokku version), we recommend a fresh install on a new server.
Before upgrading, check the migration guides to get comfortable with new features and prepare your deployment to be upgraded.
If Dokku was installed via apt-get install dokku or bootstrap.sh (most common), upgrade with:
# update your local apt cache
sudo apt-get update
# stop each running app
# for 0.8.1 and newer versions, use
dokku --quiet apps:list | xargs -L1 dokku ps:stop
# for older versions, use
dokku --quiet apps | xargs -L1 dokku ps:stop
# update dokku and it's dependencies
sudo apt-get install -qq -y dokku herokuish sshcommand plugn
# rebuild all of your applications
dokku ps:rebuildall # rebuilds all applicationsIf you have any applications deployed via the
tagsortarcommands, do not run theps:rebuildallcommand, and instead triggerps:rebuildmanually for eachgit-deployed application:dokku ps:rebuild APPPlease see the images documentation and tar documentation for instructions on rebuilding applications deployed by those plugins.
If you installed Dokku from source (less common), upgrade with:
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 applicationsTo upgrade herokuish from source, upgrade with:
