Documentation

Getting Started

Installing

To install iSulad, you can use rpm or yum package manager command with openEuler repository.

Or write repository file by hand:

cat << EOF > /etc/yum.repos.d/openEuler.repo
[openEuler]
baseurl=https://repo.openeuler.org/openEuler-20.03-LTS/OS/\$basearch
enabled=1
EOF

Install iSulad with yum:

yum install -y iSulad

if you found this error

Repository 'openEuler' is missing name in configuration, using id.

You have enabled checking of packages via GPG keys. This is a good thing.
However, you do not have any GPG public keys installed. You need to download
the keys for packages you wish to install and install them.
You can do that by running the command:
    rpm --import public.gpg.key


Alternatively you can specify the url to the key you would like to use
for a repository in the 'gpgkey' option in a repository section and YUM
will install it for you.

For more information contact your distribution or package provider.

you should run rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-openEuler first

Configure

Configure the container image registry address, for example "docker.io" or other registry addrss.

# cat /etc/isulad/daemon.json
.....
    "registry-mirrors": [
        "docker.io"
    ],
.....

We provide systemd service to start iSulad:

systemctl restart isulad # restart the server with systemd command

You can use direct command to start iSulad server:

$ sudo isulad  # run the server with default socket name and default log level and images manage function

    $ sudo isula ps -a

    Create a container with busybox named test:

    # create a container 'test' with image busybox
    $ sudo isula create -t -n test busybox

    Start this container test:

    # start the container 'test'
    $ sudo isula start test

    Kill the container test:

    # kill the container 'test':
    $ sudo isula kill test

    Remove the container test:

    # remove the container 'test'
