| 8 | <p>Sometimes it's the little things.</p> | ||
| 9 | <p>Sometime this last year we added support to | ||
| 10 | <a href='http://docs.openstack.org/developer/python-openstackclient/'> | ||
| 11 | python-openstackclient | ||
| 12 | </a> | ||
| 13 | for using | ||
| 14 | <a href='http://docs.openstack.org/developer/os-client-config/'> | ||
| 15 | os-client-config</a> | ||
| 16 | based configuration. Doesn't that sound | ||
| 17 | exciting? It should - because it means you can put your 15 OpenStack | ||
| 18 | public cloud accounts into ~/.config/openstack/clouds.yaml and refer to | ||
| 19 | them by name. Like this:</p> | ||
| 20 | <pre><code> | ||
| 21 | clouds: | ||
| 22 | vexxhost: | ||
| 23 | profile: vexxhost | ||
| 24 | auth: | ||
| 25 | project_name: d8af8a8f-a573-48e6-898a-af333b970a2d | ||
| 26 | username: 0b8c435b-cc4d-4e05-8a47-a2ada0539af1 | ||
| 27 | password: XXXXXXXXXXXXXXXXXX | ||
| 28 | region_name: ca-ymq-1 | ||
| 29 | ovh: | ||
| 30 | profile: ovh | ||
| 31 | auth: | ||
| 32 | username: 6WjmCk3Kbe5v | ||
| 33 | password: XXXXXXXXXXXXXXXXX | ||
| 34 | project_name: 3614264792735868 | ||
| 35 | regions: | ||
| 36 | - SBG1 | ||
| 37 | - GRA1 | ||
| 38 | </code></pre> | ||
| 39 | |||
| 40 | <p>The profile entry in the file is a reference to | ||
| 41 | <a href='http://docs.openstack.org/developer/os-client-config/vendor-support.html'>known cloud vendors</a> so that you can take advantage of us | ||
| 42 | knowing things like their AUTH_URL and whether they use tasks or PUT | ||
| 43 | for image uploads</p> | ||
| 44 | |||
| 45 | <p>The neat thing about all that is that you can then just say:</p> | ||
| 46 | |||
| 47 | <pre><code> | ||
| 48 | openstack --os-cloud=vexxhost server list | ||
| 49 | openstack --os-cloud=vexxhost --os-region-name=SBG1 server list | ||
| 50 | </code></pre> | ||
| 51 | |||
| 52 | <p>to interact with your cloud accounts. The exact same config file | ||
| 53 | can also drive your ansible playbooks, so you cn do:</p> | ||
| 54 | <pre><code> | ||
| 55 | --- | ||
| 56 | - hosts: localhost | ||
| 57 | connection: local | ||
| 58 | gather_facts: False | ||
| 59 | tasks: | ||
| 60 | - os_keypair: | ||
| 61 | cloud: vexxhost | ||
| 62 | name: mordred | ||
| 63 | state: present | ||
| 64 | </code></pre> | ||
| 65 | |||
| 66 | <p>Followed by:</p> | ||
| 67 | <pre><code> | ||
| 68 | openstack --os-cloud=vexxhost openstack keypair show mordred | ||
| 69 | </code></pre> | ||
| 70 | |||
| 71 | <p>When you need to poke around manually.</p> | ||
| 72 | |||
| 73 | <h3>That's still too much typing</h3> | ||
| 74 | |||
| 75 | <p>If you're like me, that's still too much of a pain. So I added the | ||
| 76 | following to my bashrc:</p> | ||
| 77 | |||
| 78 | <pre><code> | ||
| 79 | if [ "$color_prompt" = yes ]; then | ||
| 80 | PS1='${debian_chroot:+($debian_chroot)}${OS_CLOUD:+${OS_CLOUD}:}${OS_REGION_NAME:+${OS_REGION_NAME}:}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ ' | ||
| 81 | else | ||
| 82 | PS1='${debian_chroot:+($debian_chroot)}${OS_CLOUD:+${OS_CLOUD}:}${OS_REGION_NAME:+${OS_REGION_NAME}:}\u@\h:\w\$ ' | ||
| 83 | fi | ||
| 84 | |||
| 85 | function use { | ||
| 86 | declare -a CloudRegion=(${1//:/ }) | ||
| 87 | export OS_CLOUD=${CloudRegion[0]} | ||
| 88 | export OS_REGION_NAME=${CloudRegion[1]} | ||
| 89 | } | ||
| 90 | </code></pre> | ||
| 91 | |||
| 92 | <p>Which got me this:</p> | ||
| 93 | <pre><code> | ||
