These images make the build of the firmware and the generation of the DFU file for OTA quite easy, as well as preventing clashes with any other toolchains or development environments you may have installed. Based on Ubuntu 18.04 with the following build dependencies: -When this is done, a new image named *infinitime-build* is available. * ARM GCC Toolchain * nRF SDK * MCUBoot * adafruit-nrfutil -## Run a container to build the project: +## Run a container to build the project + The `infinitime-build` image contains all the dependencies you need. The default `CMD` will compile sources found in `/sources`, so you need only mount your code. This example will build the firmware, generate the MCUBoot image and generate the DFU file. Outputs will be written to **/build/output**: ```bash -$ cd # e.g. cd ./work/Pinetime -$ docker run --rm -it -v $(pwd):/sources infinitime-build -``` - -* `--rm` to delete the container after we're done. Build cache will be written out to host disk, so no worries. -* `-it` for better interactivity with the running container. - * `-i` Interactive - required if you want to send CTRL+C - * `-t` TTY - This lets colours work nicely etc? -* `-v` for mounting a volume to the container - -Output files (and the cmake build cache) will have `uid`/`gid` not matching your host user. To override them, use `docker run` like this: - -```bash -$ docker run --rm -it -v $(pwd):/sources \ - -e USER_ID=$(id -u) -e GROUP_ID=$(id -g) \ - infinitime-build +cd # e.g. cd ./work/Pinetime +docker run --rm -it -v $(pwd):/sources infinitime-build ``` If you only want to build a single CMake target, you can pass it in as the first parameter to the build script. This means calling the script explicitly as it will override the `CMD`. Here's an example For `pinetime-app`: ```bash -$ docker run --rm -it -v $(pwd):/sources infinitime-build /opt/build.sh pinetime-app +docker run --rm -it -v $(pwd):/sources infinitime-build /opt/build.sh pinetime-app ``` +The image is built using 1000:1000 for the user id and group id. If this is different to your user or group ids (run `id -u` and `id -g` to find out what your id values are if you are unsure), you will need to override them via the `--user` parameter in order to prevent permission errors with the output files (and the cmake build cache). + +Running with this image is the same as above, you just specify the ids to `docker run` + +```bash +docker run --rm -it -v $(pwd):/sources --user $(id -u):$(id -g) pfeerick/infinitime-build +``` + +Or you can specify your user id and group id (by number, not by name) directly: + +```bash +docker run --rm -it -v $(pwd):/sources --user 1234:1234 infinitime-build +``` + +## Using the image from Docker Hub + +The image is avaiable via Docker Hub for both the amd64 and arm64v8 architectures at [pfeerick/infinitime-build](https://hub.docker.com/repository/docker/pfeerick/infinitime-build). + +It can be pulled (downloaded) using the following command: + +```bash +docker pull pfeerick/infinitime-build +``` + +The default `latest` tag *should* automatically identify the correct image architecture, but if for some reason Docker does not, you can specify it manually: + +* For AMD64 (x86_64) systems: `docker pull pfeerick/infinitime-build:amd64` + +* For ARM64v8 (ARM64/aarch64) systems: `docker pull pfeerick/infinitime-build:arm64v8` + ## Build the image -The image is not (yet) available on DockerHub, you need to build it yourself, but that is quite easy.

Specifying them is not mandatory, as this can be over-ridden at build time via the `--user` flag, but doing so will make the command you need to run later a bit shorter. In the below examples, they are set to your current user id and group id automatically. You can specify them manually, but they must be specified by number, not by name. ```bash -docker image build -t infinitime-build \ - --build-arg USER_ID=$(id -u) \ - --build-arg GROUP_ID=$(id -g) \ - ./docker +docker image build -t infinitime-build --build-arg PUID=$(id -u) --build-arg PGID=$(id -g) ./docker ``` diff --git a/docker/Dockerfile b/docker/Dockerfile index 8f56356c..7f0fb4b0 100644 --- a/docker/Dockerfile +++ b/docker/Dockerfile @@ -1,16 +1,24 @@ FROM ubuntu:18.04 -RUN \ - apt-get update -qq && \ - apt-get install -y \ +ARG DEBIAN_FRONTEND=noninteractive +RUN apt-get update -qq \ + && apt-get install -y \ # x86_64 / generic packages - bash git gosu \ - cmake make build-essential \ - wget unzip \ - python3 python3-pip \ + bash \ + build-essential \ + cmake \ + git \ + make \ + python3 \ + python3-pip \ + tar \ + unzip \ + wget \ # aarch64 packages - libffi-dev libssl-dev python3-dev \ - && rm -rf /var/lib/apt/lists/*; + libffi-dev \ + libssl-dev \ + python3-dev \ + && rm -rf /var/cache/apt/* /var/lib/apt/lists/*; RUN pip3 install adafruit-nrfutil @@ -25,13 +33,10 @@ RUN bash -c "source /opt/build.sh; GetNrfSdk;" # McuBoot RUN bash -c "source /opt/build.sh; GetMcuBoot;" -# Set and arg and use it in the env for power to override at build AND runtime -ARG USER_ID=33333 -ARG GROUP_ID=33333 -ENV USER_ID $USER_ID -ENV GROUP_ID $GROUP_ID +ARG PUID=1000 +ARG PGID=1000 +RUN groupadd --system --gid $PGID infinitime && useradd --system --uid $PUID --gid $PGID infinitime +USER infinitime:infinitime ENV SOURCES_DIR /sources -COPY entrypoint.sh /opt/ -ENTRYPOINT ["/opt/entrypoint.sh"] CMD ["/opt/build.sh"] diff --git a/docker/build.sh b/docker/build.sh index 1c697d40..48dd9f33 100755 --- a/docker/build.sh +++ b/docker/build.sh @@ -27,7 +27,7 @@ main() { mkdir -p "$BUILD_DIR" CmakeGenerate - CmakeBuild "$target" + CmakeBuild $target if [[ "$DISABLE_POSTBUILD" != "true" ]]; then source "$BUILD_DIR/post_build.sh" @@ -67,7 +67,7 @@ CmakeGenerate() { CmakeBuild() { local target="$1" [[ -n "$target" ]] && target="--target $target" - cmake --build "$BUILD_DIR" --config $BUILD_TYPE "$target" -- -j$(nproc) + cmake --build "$BUILD_DIR" --config $BUILD_TYPE $target -- -j$(nproc) } [[ $SOURCED == "false" ]] && main "$@" || echo "Sourced!" \ No newline at end of file diff --git a/docker/entrypoint.sh b/docker/entrypoint.sh deleted file mode 100755 index 5adb88f5..00000000 --- a/docker/entrypoint.sh +++ /dev/null @@ -1,7 +0,0 @@ -#!/bin/bash -set -e -## Create a user on-the-fly before running CMD -## This allows us to override at runtime, allowing use of a pre-built docker image -addgroup --gid $GROUP_ID user -adduser --disabled-password --gecos '' --uid $USER_ID --gid $GROUP_ID user -exec gosu user:user /bin/bash -c "$@" \ No newline at end of file
