Openstack configuration for a project by Horizon UI

We are going to create one tenant. one tenant is one project. Openstack has an admin project by default. but I will only use the admin project to manage OpenStack Platform. All the projects will be newly created on OpenStack Platform.

 

<Concept>

External = Provider

Internal = Tenant(Project)

 

Tenant concept

 

<Project Creation>

1. Identity > Projects > Create Project

 

2. Name : Demo1 > Create Project

You can see the created project(tenant)

 

<User creation>

1. Identity > Users > Create User

 

2. Set UserName, Password, Confirm Password, Prime Project(in this case Demo1), Role > Create User

Role : _member_ = this user can only manage a Demo1 tenant. it's normal user.

        admin = this authority can manage not only tenant but also Openstack Platform like a superuser.

3. Check up the created User

 

 

<Flavor creation>

1. Admin > Compute > Flavors > Create Flavor

Flavor is a selection of VM resource volume. Openstack has five flavors by default.

We are going to create our own Flavor.

Default Flavors

2. Set name, VCPU, RAM, DISK, SWAP DISK > Create Flavor

This is for a very tiny VM.

 

3. Check up the created Flavor

 

 

<Image creation>

1. Admin > Images > Create Image

 

2. Set the Image Name, file, Format, Visibility, Protected > Create Image.

CirrOS is a linux for a test. you can get this image from this link cirros-0.5.1-x86_64-disk.img.

 

Note: In a CirrOS image, the login account is cirros. The password is gocubsgo. Since the fixed PW allows anyone to login, you should not run this image with a public IP attached. <www.docs.openstack.org/image-guide/obtain-images.html#cirros-test>

 

Format : QCOW2 is more suitable than other types if the hypervisor is QEMU

Visibility : Public. it means this image can be used for other projects.

Protected : Prevent image from being deleted

 

3. Check up the created image

 

 

Done!
