Enabling the App

After creating the systemd service recipe, it is important to install the package to the image.

In meta-subscriber-overrides is recipes-samples/images/lmp-factory-image.bb with the variable CORE_IMAGE_BASE_INSTALL.

To install a package to the image, append this variable with the package name.

For this example, add shellhttpd and netcat. As the Linux® microPlatform does not include curl, let us include curl as well.

Tip

This tutorial installs curl as a package to illustrate how packages can be added to the platform. In practice, you can also install curl as a container. Installing as a container rather than directly on the platform may be simpler and take less time.

Edit recipes-samples/images/lmp-factory-image.bb and append CORE_IMAGE_BASE_INSTALL:

cd ..
gedit recipes-samples/images/lmp-factory-image.bb
