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:
sudo apt-get update dokku apps dokku ps:stop <app> # repeat to shut down each running app sudo apt-get install -qq -y dokku herokuish dokku ps:rebuildall # restart all applications
If you installed dokku from source (less common), upgrade with:
dokku apps dokku ps:stop <app> # repeat to shut down 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 # restart all applications
To upgrade herokuish from source, upgrade with:
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
