View Help & Flags

To see help information and a list of all flags for any command, simply use the -h flag:

devspace -h # Shows all major commands and flags

devspace dev -h # Shows sub-commands and specific flags for this command

Project-Specific Commands

devspace.yaml required

The project-specific commands require that your project is already initialized, i.e. there is a devspace.yaml config file.

Start Development

This command deploys the project and then starts the development mode:

devspace dev

Deploy Project

This command deploys the project to Kubernetes:

devspace deploy # -p / --profile production => see: devspace list profiles

Run this command to just build, tag and push all images to a registry without deploying the project:

devspace build

Port Forwarding

To get a list of all ports that are being forwarded as defined in devspace.yaml, run:

devspace list ports

Commands

This command lists all available command:

devspace list commands

Use this command to run one of the custom commands:

devspace run command [command-name] -- --some-flag --another-flag=value

Profiles

This command lists all available profiles:

devspace list profiles

Use this command to switch to a different profile:

devspace use profile [optional:profile-name]

Use the -p flag to just run a single command with a different profile without switching it permanently:

devspace deploy -p [profile-name]

Use this command to print the config after a profile has been applied:

devspace print -p [profile-name]

Variables

This command lists all variables as well as their values:

devspace list vars

To change the value of a variable, run:

devspace set var VAR_NAME=value # VAR_NAME_2=value2 VAR_NAME_3=value3

Use this command to reset all variables, i.e. delete variable values from the variable cache:

devspace reset vars

Use this command to print the config after all variables have been replaced:

devspace print

Dependencies

Use this command to update git-based dependencies:

devspace update dependencies

This command performs a git fetch && git pull for all git-based dependencies.

Use this command to clear the dependencies cache:

devspace reset dependencies

Open Project

This command opens the current project in the browser:

devspace open

Must be deployed

This command requires that the project has already been deployed.

General Purpose Commands

Open UI

This command opens the localhost development UI:

devspace ui

Development Mode

The localhost development UI starts automatically in the background when running: devspace dev

Stream Logs

This command streams logs of a container:

devspace logs

Terminal & Commands

This command opens an interactive terminal session for a container:

devspace enter

To run just a single command inside a container, use:

devspace enter -- my-command --my-flag=my-value ...

File Sync

This command starts an on-demand file synchronization between localhost and a container:

devspace sync

Development Mode

If file sync is configured in your project, it automatically starts when running: devspace dev

---

Clusters & Namespaces

This command sets a different namespace as default namespace for the current kube-context/cluster:

devspace use namespace [optional:namespace]

Not for Spaces

The command devspace use namespace does not work for Loft spaces. Use devspace use space instead.

This command creates a new space using Loft:

devspace create space [space-name]

This command switches to a different spaces:

devspace use space [optional:space-name]

This command switches to a different kube-context/cluster:

devspace use context [optional:context-name]

Advanced

Clean up Images

When using Docker for image building, disk space on your local computer can get sparse after a lot of Docker builds. DevSpace provides a convenient command to clean up all images that were built with your local Docker daemon using DevSpace. This command does not remove any pushed images remotely and just clears local images and space.

In order to clean up all created images locally, simply run the following command in your project folder:

devspace cleanup images

Clean up Docker

In addition, it also makes sense to prune your Docker environment to free additional space with the following command:

docker system prune

This command will remove:

• all stopped containers
• all networks not used by at least one container
• all dangling images
• all build cache

These commands should free up a lot of space for new image builds to come.
