Customizing Your Dev Container

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

CMake version: The version of cmake to install. (Default: 3.31.6)
- Docker ARG: CMAKE_VERSION
- Host Environment Variable: OTEL_CPP_DEVCONTAINER_CMAKE_VERSION
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
abseil-cpp version: This is the version of abseil-cpp that will be used to build protobuf, gRPC, and opentelemetry-cpp.
- Docker ARG: ABSEIL_CPP_VERSION
- Host Environment Variable: OTEL_CPP_DEVCONTAINER_ABSEIL_CPP_VERSION
Protobuf version:
- Docker ARG: PROTOBUF_VERSION
- Host Environment Variable: OTEL_CPP_DEVCONTAINER_PROTOBUF_VERSION
gRPC version:
- Docker ARG: GRPC_VERSION
- Host Environment Variable: OTEL_CPP_DEVCONTAINER_GRPC_VERSION
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"
