Install SCS Offline

Important

Copy the local repo (repo.tar) and Pause Container (k8s.gcr.io_pause_3.2.tar) to the RHEL/CentOS 7 or RHEL/Rocky Linux 8 server to install SCS Server 15.

Create a new working directory for the SCS Installation.
mkdir /root/datacore
Copy repo.tar and k8s.gcr.io_pause_3.2.tar to “/root/datacore/”.
Create a local repo - “/etc/yum.repos.d/local.repo”.
[local] name=Everything we need to install scs baseurl=file:///root/datacore/packages enabled=true gpgcheck=0
Create a local repo for installing Podman. Example: “/etc/yum.repos.d/podman.repo“.

Note

Verify the file name matches exactly.

[podman]
name=Dependencies for install podman 3.0.1
baseurl=file:///root/datacore/podman_packages
enabled=true
gpgcheck=0

Disable base, updates, extras, and CentOSPlus repositories. Add enable=0 to [base], [updates], [extras], and [centosplus] session of “/etc/yum.repos.d/CentOS-Base.repo” or rename it.
Flush repo metadata.
Install an NTP Server. Do not use Active Directory as an NTP Server Source.
“The W32Time service is not a full-featured NTP solution that meets time-sensitive application needs.”
“The W32Time service cannot reliably maintain sync time to the range of 1 to 2 seconds. Such tolerances are outside the design specification of the W32Time service.”
From Microsoft KB 939322
Configure sync with local NTP Server.

Tip

NTP does not sync with the Active Directory.

Add below hosts records to /etc/hosts

Install Podman 3.0.1.
Verify the Podman 3.0.1 installation is successful.
The podman version should be 3.0.1
Load Pause Container.
Verify the Pause Container is loaded and the container TAG label is 3.2.
