You can create new Development Environments from containerized tools. The tool images can be present:
dem list --local --tool
- in registry:
dem list --all --tool
As an example let's create another, alternative Environment for our target with the following elements:
- Build system: cmake
- Toolchain: gnu-arm-none-eabi
- Debugger and deployer: stlink-org
- Test environment: dummy test
Obtaining the cmake, gnu-arm-none-eabi and stlink-org tool images
These tools are available in the axem registry. The cmake and GNU-arm-toolchain are present in the
same container image alongside with make:
The stlink-org has its own image:
Obtaining the dummy test tool image
You can use your own tools that you containerized by yourself in Development Environments created with DEM. To see how to do it, we containerize a dummy test tool. (This won't be an actual test environment, just a script that prints "test environment" .)
Let's create a directory for building the dummy test tool!
mkdir dummy_test cd dummy_test
Create a shell script that will run inside the container.
Set the dummy_test.sh, file to be executable.
chmod +x dummy_test.sh
Create a file called
Dockerfile (without extension) that describes how to build this dummy image.
Build the Docker container image.
docker build -t dummy_test:latest .
Now run the script inside a container to ensure everything works as expected.
docker run dummy_test /bin/sh -c "./dummy_test.sh"
Create the new Environment
To start the interactive Development Environment creation you need to use the
dem create command.
dem create alt_env
You will see the available tool types. Select all of them with .
Select next when you finished.
Next, you will go through all the selected tool types one-by-one and you can select the required tool image for all of them, by pressing .
- build system:
- test framework:
That's it! Now you have a new Development Environment.
Share your new Development Environment
A very important feature of DEM is to provide a reliable way to share Development Environments. To
make every member of an organization use the same toolset, the best way is to provide the
Development Environment from a catalog.
If you would like to share your Development Environment with someone directly, DEM has your back! A Development Environment descriptor can be exported to a file in JSON format, which then can be loaded to another host.
The exported file only contains the Development Environments descriptor in JSON format. The other host needs access to all required registries for successful installation.
If you'd like to share the newly created alt_env, first export it:
dem export alt_env alt_env.json
This will create the alt_env.json file in your current directory.
On the other host, the Development Environment descriptor can be loaded:
dem load alt_env.json
