Docker Tooling

Dockerfile Editor

This is an external contribution, brought by Tobias Verbeke and his team from Open Analytics. The Dockerfile Editor provides users with content assist on the commands (ADD, COPY, RUN, etc.) as well as a customizable syntax highlighting.

Executing shell in a container

Users can be given access to a shell environment within the container even if the container has a service running in the foreground. This is particularly useful for examining the container, and for debugging purposes.

Running privileged containers

Containers can be run with the --privileged flag, which gives them extended privileges, such as accessing all devices, and allowing them nearly all the same access to the host as regular processes running on the host (i.e., not in containers).

Supporting disconnections

Sometimes the Docker instances that were configured in Eclipse are not running anymore (the Docker Machine is stopped, for example). In that case, the Docker Explorer view will display a different decorator for those connections, and an "Enable connection" button in the toolbar will let the user reconnect.

Editing connection settings

A new wizard lets the user edit the connection name, and settings. This is particularly useful when the connection belongs to a Docker Machine whose IP address changed upon restart.

Pushing/Pulling/Searching for Authenticated Registries

Support now exists for performing actions upon Docker registries using authentication credentials. Users can simply set their credentials in the workspace preference page (Docker -> Registry Accounts).

These credentials may be accessed through the Registry/Account combo box in the Push/Pull Wizards. The location of a registry can also be entered manually if it doesn't require any credentials.
