TUI Tools and wrappers that simplify working with IT environments for data intensive science (HPC, containers, virtual machines)
- osc-server is a tool to quickly spin up servers in Openstack
osc-server is a simple wrapper for the openstack cli. After you get your openstack project assigned you have to execute about 10 steps for configuring network, router, IPs, images, keys, VM before you can actually login to your first virtual server. osc-server reduces this to a single step after you have configured your ~/.openstackrc file.
> osc-server
***** WARNING: ~/.openstackrc file missing ! *****
Log in to the Openstack Horizon Dashboard. Navigate to Project -> API Access
to download the OpenStack RC file. (In older Openstack versions this is in
Project -> Compute -> Access & Security -> API Access)
Save the file in your home as ~/.openstackrc and run "chmod 600 ~/.openstackrc"
To avoid a password prompt each time you use openstack you can comment the 2
lines containing OS_PASSWORD_INPUT and add a line "export OS_PASSWORD=<password>"
osc-server help shows all possible sub commands, for example you can always download a new QCOW2 Linux image directly into the system with osc-server newimage <URL> <Image-Name>
>osc-server help
*** osc-server - a tool to quickly create openstack servers ***
execute one of these sub commands:
osc-server create <server-name>
osc-server delete <server-name>
osc-server list
osc-server checknet
osc-server nameservers
osc-server newimage <URL> <Image-Name>
osc-server projectpurge (delete all resources)
osc-server showres (show machine flavors and images)
osc-server sshkey (refresh key from .ssh/id_rsa.pub)
for example:
osc-server create -f m1.small -i "Ubuntu-22.04-LTS" myserver
> osc-server create myserver1

installing new Image, executing this command:
osc-server newimage https://cloud-images.ubuntu.com/jammy/current/jammy-server-cloudimg-amd64-disk-kvm.img Ubuntu-22.04-LTS
remove key os_key_xxxxx if exists...

create floating ip address...
create server myserver1 with size m1.small and OS Ubuntu-22.04-LTS ...
assign floating ip 10.96.11.205 to server myserver1 ... Done.
Run one of these commands:
ssh centos@10.96.11.205
ssh ubuntu@10.96.11.205
Execute this command to see console output of server myserver1:
osc console log show myserver1
osc-server projectpurge simply deletes all resources in your Openstack project
> osc-server projectpurge
This will clean out your entire openstack account, including servers, images and networks

hpctoys lpython distribution shares /tmp among multiple users. This can be a security concern in larger environments. You can use this method to isolate /tmp on login nodes.
