Introduced in 0.3.1
Introduced in 0.8.1. Use the
apps command for older versions.
You can easily list all available applications using the
Note that you can easily hide extra output from Dokku commands by using the
--quiet flag, which makes it easier to parse on the command-line.
Manually creating an application
A common pattern for deploying applications to Dokku is to configure an application before deploying it. You can do so via the
Once created, you can configure the application as normal, and deploy the application whenever ready. This is useful for cases where you may wish to do any of the following kinds of tasks:
- configure domain names and ssl certificates
- create and link datastores
- set environment variables
Removing a deployed app
In some cases, you may need to destroy an application, whether it is because the application is temporary or because it was misconfigured. In these cases, you can use the
apps:destroy command. Performing any destructive actions in Dokku requires confirmation, and this command will ask for the name of the application being deleted before doing so.
This will prompt you to verify the application's name before destroying it. You may also use the
--force flag to circumvent this verification process:
Destroying an application will unlink all linked services and destroy any config related to the application. Note that linked services will retain their data for later use (or removal).
Renaming a deployed app
Introduced in 0.4.7
You can rename a deployed app using the
apps:rename command. Note that the application must have been deployed at least once, or the rename will not complete successfully:
Destroying node-js-app (including all add-ons) -----> Cleaning up... -----> Building io-js-app from herokuish... -----> Adding BUILD_ENV to build environment... -----> Node.js app detected -----> Creating runtime environment ... =====> Application deployed: http://io-js-app.ci.dokku.me Renaming node-js-app to io-js-app... done
This will copy all of your app's contents into a new app directory with the name of your choice, delete your old app, then rebuild the new version of the app and deploy it. All of your config variables, including database urls, will be preserved.
Cloning an existing app
Introduced in 0.8.1
You can clone an existing app using the
apps:clone command. Note that the application must have been deployed at least once, or cloning will not complete successfully:
This will copy all of your app's contents into a new app directory with the name of your choice and then rebuild the new version of the app and deploy it. All of your config variables, including database urls, will be preserved.
If you have exposed specific ports via docker-options, added generic domains, or performed anything that cannot be done against multiple applications,
apps:clone may result in errors.
By default, Dokku will deploy this new application, though you can skip the deploy by using the
Displaying reports about an app
Introduced in 0.8.1
You can get a report about the deployed apps using the
You can run the command for a specific app also.
You can pass flags which will output only the value of the specific information you want. For example:
