iSulad
iSulad is a lightweight container runtime daemon which is designed for IOT and Cloud infrastructure.iSulad has the characteristics of light, fast and not limited by hardware specifications and architecture, and can be applied more widely.
Getting Started
Installing
To install iSulad, you can use rpm or yum package manager command with openEuler repository.
Install iSulad with yum
yum install -y iSuladRun
We provide systemd service to start iSulad
systemctl start isulad # run the server with systemd commandYou can use direct command to start iSulad server：
$ sudo isulad # run the server with default socket name and default log level and images manage functionOperations on containers:
iSulad provides command line isulad to talk with server.
Here are some sample commands to manager containers.
List all containers in your own environment:
# list containers
$ sudo isula ps -aCreate a container with busybox named test
# create a container 'test' with image busybox
$ sudo isula create -t -n test busyboxStart this container test
# start the container 'test'
$ sudo isula start testKill the container test
# kill the container 'test'
$ sudo isula kill testRemove the container test
# remove the container 'test'
$ sudo isula rm testBuild from source
Build requirements for developers are listed in build_guide

Design of testcase
About code of test
-
Now, we use shell to finish test cases of performance;
-
Future, we should have a repository which store all test cases for iSula. Such as, performance tests, validation tests and so on... It's coming soon...
