    isula-build

    isula-build is a tool provided by iSula team for building container images. It can quickly build the container image according to the given Dockerfile.

    The binary file isula-build is a CLI tool and isula-builder runs as a daemon responding all the requests from client.

    It provides a command line tool that can be used to

    • build an image from a Dockerfile
    • list all images in local store
    • remove specified images

    We also

    • be compatible with Dockerfile grammar
    • support extended file attributes, e.g., linux security, IMA, EVM, user, trusted
    • support different image formats, e.g., docker-archive, isulad

    Getting Started

    Install on openEuler

    Install from source

    For compiling from source on openEuler, these packages are required on your OS:

    • make
    • golang (version 1.13 or higher)
    • btrfs-progs-devel
    • device-mapper-devel
    • glib2-devel
    • gpgme-devel
    • libassuan-devel
    • libseccomp-devel
    • git
    • bzip2
    • go-md2man
    • systemd-devel

    You can install them on openEuler with yum:

    sudo yum install make btrfs-progs-devel device-mapper-devel glib2-devel gpgme-devel libassuan-devel libseccomp-devel git bzip2 go-md2man systemd-devel golang

    Get the source code with git:

    git clone https://gitee.com/openeuler/isula-build.git

    Please note that isula-build uses Go Modules to manage vendoring packages. Before compiling please make sure you can connect to the default goproxy server.

    If you are working behind a proxy, please refer to Go Module Proxy by setting GOPROXY=yourproxy.

    Enter the source code directory and begin compiling:

    cd isula-build
    sudo make

    After compiling success, you can install the binaries of isula-build to /usr/bin/ simply with:

    sudo make install

    To run the server of isula-build for the first time, the default configuration files should be installed:

    sudo mkdir -p /etc/isula-build/ && \
    install -p -m 600 ./cmd/daemon/config/configuration.toml /etc/isula-build/configuration.toml && \
    install -p -m 600 ./cmd/daemon/config/storage.toml /etc/isula-build/storage.toml && \
    install -p -m 600 ./cmd/daemon/config/registries.toml /etc/isula-build/registries.toml && \
    install -p -m 600 ./cmd/daemon/config/policy.json /etc/isula-build/policy.json

    Install as RPM package

    isula-build is integrated with openeuler/isula-kits, for details on how to compile and install isula-build as RPM package, please refer to isula-kits.

    Run the daemon server

    Run as system service

    To manage isula-builder by systemd, please refer to following steps:

    sudo install -p -m 640 ./isula-build.service /etc/systemd/system/isula-build.service
    sudo systemctl enable isula-build
    sudo systemctl start isula-build

    Example on building container images

    Requirements

    For building container images, runc is required.

    You can get runc by the help of installing docker or docker-runc on your openEuler distro by:

    sudo yum install docker

    or

    sudo yum install docker-runc

    Building image

    Here is an example for building a container image, for more details please refer to usage.

    Create a simple buildDir and write the Dockerfile

    FROM alpine:latest
    LABEL foo=bar
    COPY ./* /home/dir1/

    Build the image in the buildDir

    $ sudo isula-build ctr-img build -f Dockerfile .
    STEP  1: FROM alpine:latest
    STEP  2: LABEL foo=bar
    STEP  3: COPY ./* /home/dir1/
    Getting image source signatures
    Copying blob sha256:e9235582825a2691b1c91a96580e358c99acfd48082cbf1b92fd2ba4a791efc3
    Copying blob sha256:dc3bca97af8b81508c343b13a08493c7809b474dc25986fcbae90c6722201be3
    Copying config sha256:9ec92a8819f9da1b06ea9ff83307ff859af2959b70bfab101f6a325b1a211549
    Writing manifest to image destination
    Storing signatures
    Build success with image id: 9ec92a8819f9da1b06ea9ff83307ff859af2959b70bfab101f6a325b1a211549

    Listing images

    $ sudo isula-build ctr-img images
