using ansible to do status checks on systems from remote
 

Want to check on a set of hosts but you don't have root/sudo access on
lockbox?
Want to do it in a way that you can hit the host quickly w/o having to do
them one by one?


Here's how you can use ansible from your local computer to do it:

1. check out ansible:
git clone git://github.com/ansible/ansible.git

2. get a copy of our host inventory:
ssh lockbox01 "pushd /srv/web/infra/hosts>>/dev/null; for host in
*.org; do echo $host; done" >> ~/fedora-inv

3. make sure your ~/.ssh/config file lets you bounce through bastion for
fedora hosts:


Host *.phx2.fedoraproject.org *.vpn.fedoraproject.org *.qa.fedoraproject.org
IdentityFile ~/.ssh/fedora-rsa
VerifyHostKeyDNS yes
ProxyCommand ssh -q bastion.fedoraproject.org nc %h %p

4. cd into the ansible checkout dir:

5. setup the ansible environment:

. ./hacking/env-setup

6. run your commands like this:
ansible -c ssh -u skvidal -i ~/fedora-inv app??.phx2* -a uptime

that reads:
- use the ssh connectory as user skvidal with ~/fedora-inv as the
inventory file. Connect to the hosts app??.phx2* and run the command
module (the default module) with argument of "uptime"


the output looks like this:
app07.phx2.fedoraproject.org | success | rc=0 >>
21:20:34 up 3 days, 23:22, 1 user, load average: 0.00, 0.03, 0.00

app02.phx2.fedoraproject.org | success | rc=0 >>
21:20:34 up 3 days, 22:00, 5 users, load average: 2.41, 2.26, 3.27

app03.phx2.fedoraproject.org | success | rc=0 >>
21:20:34 up 1:27, 3 users, load average: 3.09, 3.89, 6.39

app04.phx2.fedoraproject.org | success | rc=0 >>
21:20:34 up 3 days, 23:24, 2 users, load average: 3.68, 3.11, 12.08

app01.phx2.fedoraproject.org | success | rc=0 >>
21:20:34 up 3 days, 21:39, 7 users, load average: 1.80, 2.03, 8.66



please do try to use this sensibly :)
