Hi everyone, I have an application that already exist so how could I implemented it on openstack????? I have a sales application based on ROA architecture and this application is already devlopped and I want to implemented it on openstack in order to improve the quality of this application. I need this for my research
You need to run your Java app on a VM created using Openstack, below is the steps to do it.
In Openstack Dashboard:
Create a Linux instance (Ubuntu) and launch the VM with internet access
Install open jdk & Eclipse IDE
Run you java app in VM using IDE.
Thanks.
When I lauch an instance with: nova boot --image 30799aa2-5f4d-4a27-ae0b-98f32f1a065a --flavor m1.medium --key_name lxplus doctest2 I got this error: ERROR: Invalid key_name provided. (HTTP 400) (Request-ID: req-52e903dd-638d-4b09-905d-1c9d6817e901) Could you help me please
When I lanch the image tha I have create I get this error (/var/log/nova/nova-compute.log) ERROR nova.openstack.common.periodic_task [-] Error during ComputeManager._instance_usage_audit: Remote error: DBError SQLite DateTime type only accepts Python datetime and date objects as input. (original cause: TypeError: SQLite DateTime type only accepts Python datetime and date objects as input.) u'INSERT INTO task_log (created_at, updated_at, deleted_at, deleted, task_name, state, host, period_beginning, period_ending, message, task_items, errors) Any help please
Hi, As you launch the VM instance using CLI, you can also pass user-data in yaml format. This can help you install the jdk, eclipse packages and then start the application of your choice - so that you do not have any manual steps after the instance comes up, and your service is ready! You may even choose to set ssh-keys, sudo etc. for your choice of user on the VM instance using cloud-init user-data.
The user-data is passed in form of config-drive, and cloud-init is the software, in Linux distro, which processes the yaml file and act onto that.
For further information on cloud-init please check,

What kind of application you are talking about ? Have Openstack Nodes been already setup and functional ?
Yes the controller node and the compute node are already set (I'm workng with legacy network). A java application
Can you better explain your question? What type of application do you have, which is its architecture, how openstack will interact with it (simply hosting application related VM, instantiating a deployment of the application through HEAT)...
Please be more clear, you can reedit your question and its title.
