== Cloud information == The dashboard for the production cloud instance is: You can download credentials via the dashboard (under security and access) === Transient instances === Transient instances are short term use instances for Fedora contributors. They can be terminated at any time and shouldn't be relied on for any production use. If you have an application or longer term item that should always be around please create a persistent playbook instead. (see below) to startup a new transient cloud instance and configure for basic server use run (as root): sudo -i ansible-playbook /srv/web/infra/ansible/playbooks/transient_cloud_instance.yml -e 'name=somename' The -i is important - ansible's tools need access to root's sshagent as well as the cloud credentials to run the above playbooks successfully. This will setup a new instance, provision it and email sysadmin-main that the instance was created and it's ip address. You will then be able to login, as root if you are in the sysadmin-main group. (If you are making the instance for another user, see below) You MUST pass a name to it, ie: -e 'name=somethingdescriptive' You can optionally override defaults by passing any of the following: image=imagename (default is centos70_x86_64) instance_type=some instance type (default is m1.small) root_auth_users='user1 user2 user3 @group1' (default always includes sysadmin-main group) Note: if you run this playbook with the same name= multiple times openstack is smart enough to just return the current ip of that instance and go on. This way you can re-run if you want to reconfigure it without reprovisioning it.

These are things like dev instances for various applications, proof of concept servers for evaluating something, etc. They will be reprovisioned after a reboot/maint window for the cloud. Setting up a new persistent cloud host: 1) Select an available floating IP source /srv/private/ansible/files/openstack/novarc nova floating-ip-list Note that an "available floating IP" is one that has only a "-" in the Fixed IP column of the above `nova` command. Ignore the fact that the "Server Id" column is completely blank for all instances. If there are no ip's with -, use: nova floating-ip-create and retry the list. 2) Add that IP addr to dns (typically as 3) Create persistent storage disk for the instance (if necessary.. you might not need this). nova volume-create --display-name SOME_NAME SIZE_IN_GB 4) Add to ansible inventory in the persistent-cloud group. You should use the FQDN for this and not the IP. Names are good. 5) setup the host_vars file. It should looks something like this:: instance_type: m1.medium image: keypair: fedora-admin-20130801 security_group: default # NOTE: security_group MUST contain default. zone: nova tcp_ports: [22, 80, 443] inventory_tenant: persistent inventory_instance_name: taiga hostbase: taiga public_ip: root_auth_users: ralph maxamillion description: taiga frontend server volumes: - volume_id: VOLUME_UUID_GOES_HERE device: /dev/vdc cloud_networks: # persistent-net - net-id: "67b77354-39a4-43de-b007-bb813ac5c35f" 6) setup the host playbook 7) run the playbook: sudo -i ansible-playbook /srv/web/infra/ansible/playbooks/hosts/$YOUR_HOSTNAME_HERE.yml You should be able to run that playbook over and over again safely, it will only setup/create a new instance if the ip is not up/responding. === SECURITY GROUPS === FIXME: needs work for new cloud. - to edit security groups you must either have your own cloud account or be a member of sysadmin-main This gives you the credential to change things in the persistent tenant - source /srv/private/ansible/files/openstack/persistent-admin/ This lists all security groups in that tenant: - euca-describe-groups | grep GROUP the output will look like this: euca-describe-groups | grep GROU GROUP d4e664a10e2c4210839150be09c46e5e default default GROUP d4e664a10e2c4210839150be09c46e5e jenkins jenkins instance group GROUP d4e664a10e2c4210839150be09c46e5e logstash logstash security group GROUP d4e664a10e2c4210839150be09c46e5e smtpserver list server group. needs web and smtp GROUP d4e664a10e2c4210839150be09c46e5e webserver webserver security group GROUP d4e664a10e2c4210839150be09c46e5e wideopen wideopen This lets you list the rules in a specific group: - euca-describe-group groupname the output will look like this: euca-describe-group wideopen GROUP d4e664a10e2c4210839150be09c46e5e wideopen wideopen PERMISSION d4e664a10e2c4210839150be09c46e5e wideopen ALLOWS tcp 1 65535 FROM CIDR PERMISSION d4e664a10e2c4210839150be09c46e5e wideopen ALLOWS icmp -1 -1 FROM CIDR To create a new group: euca-create-group -d "group description here" groupname To add a rule to a group: euca-authorize -P tcp -p 22 groupname euca-authorize -P icmp -t -1:-1 groupname To delete a rule from a group: euca-revoke -P tcp -p 22 groupname Notes: - Be careful removing or adding rules to existing groups b/c you could be impacting other instances using that security group. - You will almost always want to allow 22/tcp (sshd) and icmp -1 -1 (ping and traceroute and friends). === TERMINATING INSTANCES === For transient: 1. source /srv/private/ansible/files/openstack/transient-admin/ - OR - For persistent: 1. source /srv/private/ansible/files/openstack/novarc 2. nova list | grep <ip of your instance or name of your instance> 3. nova delete <name of instance or ID of instance>
