New subject: [TripleO] Offline Installation Support

23 Mar 2022

      Hi Harald,

Thanks for sharing the steps and apologies for the late reply.

I tried setting up Local Repo Server and Registry Server on one machine.
Using that I successfully deployed Openstack Ussuri Undercloud and
Overcloud in an offline mode.

Now, in order to test Upgrade from USSURI to VICTORIA, I updated the repo
file and podman registry at my local server for Victoria.
On Undercloud , repo file content is as follows:

[tripleo]
baseurl = http://30.30.30.8/software/repos/tripleo_victoria
enabled = 1
gpgcheck = 0
module_hotfixes=1
name = tripleo

where 30.30.30.8 is the IP of my reposerver.

With this I have successfully updated the required packages using the
command:
*sudo yum update python*-tripleoclient openstack-tripleo-common
openstack-tripleo-heat-templates*

Also the container image prepare file, now has the following content
parameter_defaults:
  ContainerImagePrepare:
  - push_destination: true
    set:
      name_prefix: openstack-
      name_suffix: ''
      namespace: myserver.com:5000/tripleovictoria
      neutron_driver: ovn
      rhel_containers: false
      tag: current-tripleo
    tag_from_label: rdo_version

But once I run the command "*openstack undercloud upgrade*", I get the
following error
2022-03-23 09:53:24,527 p=380392 u=root n=ansible | 2022-03-23

        "stream": "3.0"
    },
    "msg": "*No group container-tools:3.0/common available*.",
    "results": []
}

Can you please help in resolving this issue.

Hi Team,
We have successfully done POC on deploying my TripleO Train HA Setup
with Baremetal Provisioning on Overcloud Node as well.
We would like to thank Tripleo community members for helping us and
resolving all our concerns at all times.
Moving forward, we need to deploy the setup on the Lab environment for
which I need some support as well.
We don't have internet in Lab machines, all that we have is access to a
central server (staging) which has internet access and we can download
all the requirements over there.
Queries:
* Is there any feasible method to install Undercloud and Overcloud
    Machines in complete offline mode?
  * If yes, then
1. What are the steps to download all related stuff on the staging
        server?
I don't know the exact steps, and I am not aware of upstream
documentation page explaining this.
You will probalby want to use the 'rsync' tool to sync RDO RPM
repositories and create a local repo on you staging machine. Sync
packages, use `createrepo` tool to generate yum/dnf repo metadata. Then
set up a webserver to make the repository available over HTTP. Search
the internets for "Create local RPM repository / mirror", there are many
generic guides that will help you.
For containers you need to set up a local container registry. Then I
would suggest useing the `skopeo`[1] tool to sync containers from the
public registry to your local registry.
...
2. What modifications would be required in undercloud/overcloud and
        other configuration files to support this?
You need to set up the undercloud to use the RPM repositries on the
staging server. Put config in /etc/yum.repos.d/*.repo files. Once the
overcloud is deployed you would want to add the repo config there as well.
You need to use a custom containers-prepare file when deploying the
undercloud and overcloud, you must set the namespaces to point to your
local registry. Something like this:
parameter_defaults:
   ContainerImagePrepare:
   - push_destination: false
     set:
       name_prefix: openstack-
       name_suffix: ''
       namespace: staging.example.com:5000/tripleotrain
       neutron_driver: null
       tag: current-tripleo
       ...
I would suggest generating the container prepare env file with the
`openstack tripleo container image prepare` command[2] and then edit the
generated file.
