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.
