Creates derived container that runs with local rights. It's a part of the DDEN infrastructure and is a last step of creating the development environment.

It'll build a dedicated image that derives from a base development environment image and add a user that has the same user ID and group ID as the local user that starts the compilation process.

In addition, when run standalone, it acts as a snippet to show how to add user to the docker to avoid creating files as a ROOT user.

This is a very simplified combination of approaches presented in the following articles: 1, 2, 3, 4.

Use the following bash command to automatically install desired DDEN type image.

curl -Lks https://raw.githubusercontent.com/psugrg/duset/main/duset.sh \
| /bin/bash -s <image-name>

Where:

• <image-name> - the name of the DDEN type of image to be installed.

The installed image will have the following name: <image-name>-local and will be installed in ./local/bin folder.

Run the following command to create an instance of the environment. The instance (container) will be created for the current folder. This means that the current folder will be bind with the container that will be created.

~/.local/bin/<image-name>-local-create.sh <instance-name>

Where:

• <instance-name> - the name of the development environment instance (container).

Alternatively the image can be build and installed manually.

Use the following bash command to build a local image.

docker image build \
--build-arg IMAGE=<image-name>
--build-arg USER_ID=$(id -u ${USER}) \
--build-arg GROUP_ID=$(id -g ${USER}) \
--build-arg USER_NAME=${USER} \
--build-arg GROUP_NAME=${USER} \
-t <user-image-name> \
.

Where:

• <image-name> - the name of the base image you want to derive from.
• <user-image-name> - the name of the new image that will be created.

Run the following bash command to install DDEN type environment to the ~/.local/user/bin location.

docker run --rm -v "$HOME/.local/bin:/home/user/.local/bin" \ 
-e IMAGE_NAME=<user-image-name> \
<user-image-name> \
install.sh

For the standalone usage the IMAGE variable can be omitted and after the image is build, user can start an example command (bash with the interactive terminal).

docker image build \
--build-arg USER_ID=$(id -u ${USER}) \
--build-arg GROUP_ID=$(id -g ${USER}) \
--build-arg USER_NAME=${USER} \
--build-arg GROUP_NAME=${USER} \
-t duset \
.

docker run -it --rm duset /bin/bash
