A quick reference guide for commonly used Dokku commands.
1. Create and list app
# Create app
dokku apps:create <app_name>
# List app
dokku apps:list
2. Set domains
# Set app's domain
dokku domains:set <app_name> app.example.com
# Set global domain
dokku domains:set-global example.com
3. Join app to a specific network
# List all networks
dokku network:list
# Add an app to a specific network
dokku network:set <app_name> initial-network <target_network>
4. Show the app’s configuration
dokku config:show <app_name>
5. Manully restart an app
dokku ps:rebuild <app_name>
6. Bind app container to all interface
bind to all interfaces (0.0.0.0), so the container can be accessed by external request. However, the host port will be randomly assigned.
dokku network:set <app_name> bind-all-interfaces true
7. Set config
dokku config:set <app_name> DOKKU_PROXY_PORT="8080"
8. Check nginx config
dokku nginx:show-config <app_name>
9. Set port mapping
dokku proxy:ports-set <app_name> http:<host_port>:<container_port>
# Show port mapping
dokku proxy:report <app_name>
# Rebuild proxy
dokku proxy:build-config <app_name>
10. Manually enable proxy
dokku proxy:enable <app_name>
11. Set app ipv4 address
dokku nginx:set app bind-address-ipv4 127.0.0.1
# Remove the ipv4 setting
dokku nginx:set app bind-address-ipv4
