isula-build is a tool provided by the iSula team for building container images. It can quickly build a container image based on a given Dockerfile
.
The tool adopts the server + client mode. The binary file isula-build
is the client that provides a CLI for building and managing images, while isula-builder
is the server that runs as a daemon in the background, responding all the requests from client.
You can use the CLI to
In addition, the following capabilities are also provided:
For compiling from source on openEuler, these packages are required on your OS:
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
Enter the source code directory and begin compiling:
cd isula-build
sudo make
After compiling success, you can install the binaries and default configuration files simply with:
sudo make install
isula-build
is now released with update pack of openEuler 20.03 LTS, you can install it using yum or rpm. Before you install, please enable "update" in the repo file.
yum
sudo yum install -y isula-build
NOTE: Please make sure the "update" part of your yum configuration is enabled. You can download the source of yum from openEuler repo list and install it.
rpm
You can download the RPM package of isula-build and intall it.
sudo rpm -ivh isula-build-*.rpm
To manage isula-build
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
You can also run the isula-builder binary file on the server to start the service.
sudo isula-builder --dataroot="/var/lib/isula-build"
For building container images, runc
is required.
You can get runc
by installing docker
or docker-runc
on your openEuler distro:
sudo yum install docker
or
sudo yum install docker-runc
Here is an example for building a container image, for more details please refer to Usage Guidelines.
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/
