============================================
|
|
Use Container-backed Remote CLIs and Clients
|
|
============================================
|
|
|
|
Remote platform |CLIs| can be used in any shell after sourcing the generated
|
|
remote CLI/client RC file. This RC file sets up the required environment
|
|
variables and aliases for the remote |CLI| commands.
|
|
|
|
.. rubric:: |prereq|
|
|
|
|
.. _using-container-backed-remote-clis-and-clients-ul-vcd-4rf-14b:
|
|
|
|
- Consider adding the following command to your .login or shell rc file, such
|
|
that your shells will automatically be initialized with the environment
|
|
variables and aliases for the remote |CLI| commands.
|
|
|
|
Otherwise, execute it before proceeding:
|
|
|
|
.. code-block:: none
|
|
|
|
root@myclient:/home/user/remote_cli_wd# source remote_client_platform.sh
|
|
|
|
- You must have completed the configuration steps described in
|
|
:ref:`Configuring Container-backed Remote CLIs and Clients
|
|
<security-configure-container-backed-remote-clis-and-clients>`
|
|
before proceeding.
|
|
|
|
- If you specified repositories that require authentication when configuring
|
|
the container-backed remote |CLIs|, you must perform a :command:`docker
|
|
login` to that repository before using remote |CLIs| for the first time
|
|
|
|
.. rubric:: |proc|
|
|
|
|
- For simple StarlingX :command:`system` |CLI| and Kubernetes
|
|
:command:`kubectl` |CLI| commands:
|
|
|
|
.. note::
|
|
The first usage of a remote |CLI| command will be slow as it requires
|
|
that the docker image supporting the remote CLIs/clients be pulled from
|
|
the remote registry.

root@myclient:/home/user/remote_cli_wd#
|
|
|
|
.. note::
|
|
Some |CLI| commands are designed to leave you in a shell prompt, for example:
|
|
|
|
.. code-block:: none
|
|
|
|
root@myclient:/home/user/remote_cli_wd# openstack
|
|
|
|
or
|
|
|
|
.. code-block:: none
|
|
|
|
root@myclient:/home/user/remote_cli_wd# kubectl exec -ti <pod_name> -- /bin/bash
|
|
|
|
In most cases, the remote |CLI| will detect and handle these commands
|
|
correctly. If you encounter cases that are not handled correctly, you
|
|
can force-enable or disable the shell options using the <FORCE\_SHELL=true>
|
|
or <FORCE\_NO\_SHELL=true> variables before the command.
|
|
|
|
For example:
|
|
|
|
.. code-block:: none
|
|
|
|
root@myclient:/home/user/remote_cli_wd# FORCE_SHELL=true kubectl exec -ti <pod_name> -- /bin/bash
|
|
root@myclient:/home/user/remote_cli_wd# FORCE_NO_SHELL=true kubectl exec <pod_name> -- ls
|
|
|
|
You cannot use both variables at the same time.
|
|
|
|
- If you need to run a remote |CLI| command that references a local file,
|
|
then that file must be copied to or created in the working directory
|
|
specified in the -w option on the ./config\_client.sh command.
|
|
|
|
For example:
|
|
|
|
.. code-block:: none
|
|
|
|
root@myclient:/home/user# cp /<someDir>/test.yml $HOME/remote_cli_wd/test.yml
|
|
root@myclient:/home/user# cd $HOME/remote_cli_wd
|
|
root@myclient:/home/user/remote_cli_wd# kubectl -n kube-system create -f test.yml
|
|
pod/test-pod created
|
|
root@myclient:/home/user/remote_cli_wd# kubectl -n kube-system delete -f test.yml
|
|
pod/test-pod deleted
|
|
|
|
- For Helm commands:
|
|
|
|
.. code-block:: none
|
|
|
|
% cd $HOME/remote_cli_wd
|
|
|
|
.. note::
|
|
When using helm, any command that requires access to a helm
|
|
repository \(managed locally\) will require that you be in the
|
|
$HOME/remote\_cli\_wd directory and use the --home ./.helm option.
|
|
For the host local installation, it requires the users $HOME and
|
|
ends up in $HOME/.config and $HOME/.cache/helm.
|
|
|
|
.. code-block:: none
|
|
|
|
% helm --home ./.helm repo add bitnami https://charts.bitnami.com/bitnami
|
|
% helm --home ./.helm repo update
|
|
% helm --home ./.helm repo list
|
|
% helm --home ./.helm search repo
|
|
% helm --home ./.helm install wordpress bitnami/wordpress
