Viewing shared images

We can view what images have been shared for a particular tenant when someone has used the member-create option. This allows us to manage and control which users have what type of access to images in our OpenStack environment.

Getting ready

To begin with, ensure that you are logged in to our Ubuntu client where we can run the glance tool. This can be installed using the following command:

sudo apt-get update
sudo apt-get install python-glanceclient

Ensure that you have your environment variable set up correctly with our admin user and password, as created in the previous chapter:

export OS_TENANT_NAME=cookbook
export OS_USERNAME=admin
export OS_PASSWORD=openstack
export OS_AUTH_URL=https://192.168.100.200:5000/v2.0/
export OS_NO_CACHE=1
export OS_KEY=/vagrant/cakey.pem
export OS_CACERT=/vagrant/ca.pem

How to do it...

Carry out the following steps to view the images that have been shared for a particular tenant:

We first get the tenant ID of the tenant we want to view. We do this as follows:
```
keystone tenant-list 
```
We can now list the images that have been shared with that tenant ID as follows:
```
glance member-list --tenant-id \
 45c787efeaec42aa9cab522711bf5f4d
```
This produces the following output:

How it works...

The member-list option in the glance command allows us to view which images have been shared with other tenants. The syntax is as follows:

glance member-list --image-id IMAGE_ID
glance member-list –-tenant-id TENANT_ID
