Installing containers
This chapter describes container installation topics. Container installation topics include:
- Container installation prerequisites
Ensure that prerequisites are met before launching a container.
- Launching a container manually
Launches a single SR Linux container using a manual procedure.
Container installation prerequisites
Ensure that prerequisites are met before installing an SR Linux container.
Minimum system requirements:
- CentOS 7.4 system, kernel 4.17
- 8 GB RAM
- 8 core CPU
- The host machine user must have sudo privileges (preferably passwordless)
Minimum software requirements:
- Docker CE installed, minimum version 18.09:
- Python version 3.6 or later
- srlinux-vX.Y.Z-N.tar.xz file (for the SR Linux Docker image)
where X = major, Y = minor, Z = patch, and N = build number
Note: Containers that are instantiated without a license key from
Nokia are active for 14 days only.
Launching a container manually
- Copy the srlinux-vX.Y.Z-N.tar.xz file into ~/ of the CentOS 7 host machine.
-
Load the Docker image. To load the image, the user must have root privilege, or be part of
the Docker group.
$ docker image load -i ~/srlinux-vX.Y.Z-N.tar.xz
-
Check that the Docker image was imported correctly:
$ docker images

Launch an instance of the SR Linux
container on the host using the options in the following command line. This command must be
entered in a single line. See the note that follows about copying text from a PDF file without
broken lines.
$ docker run -t -d --rm --privileged \ --sysctl net.ipv6.conf.all.disable_ipv6=0 \ --sysctl net.ipv4.ip_forward=0 \ --sysctl net.ipv6.conf.all.accept_dad=0 \ --sysctl net.ipv6.conf.default.accept_dad=0 \ --sysctl net.ipv6.conf.all.autoconf=0 \ --sysctl net.ipv6.conf.default.autoconf=0 \ -u $(id -u):$(id -g) \ --name srlinux_dut1 srlinux:vX.Y.Z-N \ sudo bash -c '/opt/srlinux/bin/sr_linux'where X = major, Y = minor, Z = patch, and N = build Number for
srlinux:vX.Y.Z-NNote: Copying a long command string from a PDF file introduces line breaks. As a workaround, copy the text string and place into Notepad++. Highlight the text and select CTRL+J. The result is a single line with no returns. -
Check that the docker container has been created with the name 'srlinux':
$ docker ps

Turn off the Docker0 Tx checksum offload:
# sudo ethtool --offload docker0 tx off
-
Open an SSH session to the DUT using the following credentials:
- username: admin
- password: admin
