Customizing Your Dev Container

Customize your dev container using build arguments (for direct Docker builds) or environment variables (for evaluation in devcontainer.json).

• CXX standard: This is the C++ standard to build from (eg: 17, 20, ...). (Default: 17)

  • Docker ARG: CXX_STANDARD
  • Host Environment Variable: OTEL_CPP_DEVCONTAINER_CXX_STANDARD

• User ID (UID): User ID (Default: 1000)

  • Docker ARG: USER_UID
  • Host Environment Variable: OTEL_CPP_DEVCONTAINER_USER_UID

• Group ID (GID): User group ID (Default: 1000)

  • Docker ARG: USER_GID
  • Host Environment Variable: OTEL_CPP_DEVCONTAINER_USER_GID

• Install Packages: These are the additional packages that will be installed via apt install in the devcontainer. This is a space separated list.

  • Docker ARG: INSTALL_PACKAGES (Default: ``)
  • Host Environment Variable: OTEL_CPP_DEVCONTAINER_INSTALL_PACKAGES (Default: ``)

Examples

• docker build --build-arg CXX_STANDARD="20" --build-arg INSTALL_PACKAGES="nano gitk"...
• export OTEL_CPP_DEVCONTAINER_CXX_STANDARD=20
• export OTEL_CPP_DEVCONTAINER_INSTALL_PACKAGES="nano gitk"
