Dev Containers

Open your project with the devcontainer.json file inside the IDE.

Open the devcontainer.json file in the editor.

In the left gutter, click , select Create Dev Container and Mount Sources and select the backend IDE with which you want to work inside the container.

The following options are also available in the context menu:

• Create Dev Container and Clone Sources: use this option to clone your project into a Dev Container.

• Show Dev Containers: use this option to check a list of existing dev containers. You can see which ones are active and running, stop them, or restart them.

  

• Manage Dev Container Backends: use this option to remove the unnecessary ones from Docker shared volumes.

  

• Add Modified Settings from IDE: use this option to add your IDE settings to the IDE backend that is running inside your Dev Container. The settings are added to the devcontainer.json file as a customizations section. It might be useful if you want to synchronize both settings or choose some other customization option.

  

  You can also add the non-default application-level settings, modify the added settings options, sort them, or add properties from the JSON schema. Press Alt+Enter in the settings section of the devcontainer.json file and select the appropriate option.

  

The process of creating a Dev Container is displayed in the Services tool window.

After the Dev Container is created, click Connect.
