Validate the Local Repositories on the Airgap Server

After setting up the repositories, validate them.

Verify the Local Repository through TDNF

Configure the new repository on Photon OS and add photon-updates-internal.repo and photon-release-internal.repo to /etc/yum.repos.d/:

cat /etc/yum.repos.d/photon-updates-internal.repo 
[photon-updates-internal]
name=VMware Photon Linux $releasever ($basearch) Updates Internal 
baseurl=https://<replace-with-custom-FQDN>/updates/photon-updates/ 
gpgkey=file:///etc/pki/rpm-gpg/VMWARE-RPM-GPG-KEY
gpgcheck=1
enabled=1
skip_if_unavailable=True

cat /etc/yum.repos.d/photon-release-internal.repo 
[photon-release-internal]
name=VMware Photon Linux $releasever ($basearch) Release Internal 
baseurl=https://<replace-with-custom-FQDN>/release/photon/ 
gpgkey=file:///etc/pki/rpm-gpg/VMWARE-RPM-GPG-KEY
gpgcheck=1
enabled=1
skip_if_unavailable=True

TDNF displays the following output:

#tdnf makecache
Metadata cache created.   3578    100%


#tdnf repolist
    repo id                repo   name                			    status    
photon-updates-internal VMware Photon Linux 3.0 (x86_64) Updates Internal  enabled
photon-release-internal VMware Photon Linux 3.0 (x86_64) Release Internal  enabled

Verify Harbor and Photon Repositories

There are three methods for validating the repository on the air-gapped server:

Method 1 - Using a browser: Access the repositories from a remote client that has access to the air-gapped server through a proxy. Or, through a client that is located on the same network. Open the Web browser and enter the FQDN name and IP address of the air-gapped server. You can also access the following Photon OS repositories through the Web browser:

• Update repository: https://<replace-with-custom-FQDN>/updates/photon-updates/.
• Release repository: https://<replace-with-custom-FQDN>/release/photon/.

Note: For an optimal experience, use the Firefox browser or the Chrome browser.

Method 2 - Accessing Through TDNF:

1. Deploy another Photon OS in the air-gapped environment.
2. Move all the repository files that are under /etc/yum.repos.d/ to a different folder. For example, move all the repository files to /root and create two repository files targeting the air-gapped server:

   //Repo of photon updates
   #vim /etc/yum.repos.d/ag-photon-updates.repo 
   [ag-photon-updates]
   name=Airgap Photon Updates Repo
   baseurl=https://<replace-with-custom-FQDN>/ updates/photon-updates/
   gpgkey=file:///etc/pki/rpm-gpg/VMWARE-RPM-GPG-KEY
   gpgcheck=1
   enabled=1
   skip_if_unavailable=True
   
   //Repo of photon release
   #vim /etc/yum.repos.d/ag-photon-release.repo 
   [ag-photon-release]
   name=Airgap Photon Release Repo
   baseurl=https://<replace-with-custom-FQDN>/release/photon-release/
   gpgkey=file:///etc/pki/rpm-gpg/VMWARE-RPM-GPG-KEY
   gpgcheck=1
   enabled=1
   skip_if_unavailable=True
   

3. Save both the files and use TDNF to update them:

   #tdnf makecache
   #tdnf update
   

Method 3 - Accessing through Docker: From the deployed Photon OS virtual machine, log in to the air-gapped server and use the docker pull command:

#docker login <replace-with-custom-FQDN>:8043/registry
#docker pull <replace-with-custom-FQDN>:8043/registry/dougbtv/whereabouts:v0.4

The image pulls from the air-gapped server to the local repository.
