Clojure
Clojure-control is a clojure DSL for system admin and deployment with many remote machines via ssh.
I am pleased to annoucment that clojure-control 0.3.0 is out.It adds some powerful features in this release ,includes:
- ssh and scp both have a new option :sudo to be executed as root on remote machines,for example:
(ssh "/etc/init.d/ssh restart" :sudo true)
- scp has a new option :mode to change file modes copied from local:
(scp "start.sh" "/etc/init.d/start.sh" :sudo true :mode 755)
- A new function "exists?" to test if a file exists on remote machines:
(if (not (exists? (str "/home/deploy/.ssh")))
(ssh (sudo (str "mkdir -p /home/deploy/.ssh"))))
- Call other task in deftask with "call" function:
(deftask :ps "A task to grep process" [process]
(ssh (str "ps aux | grep " process)))
(deftask :start_ha []
(ssh "/etc/init.d/haproxy start")
(call :ps "haproxy"))
- A new function "append" to append a line to a file on remote machines:
(ssh (append "/etc/hosts" "192.168.1.100 web" :sudo true))
- A new function "sed" to replace lines in a file on remote machines,and comm/uncomm to comment/uncomment a line in a file:
(sed <file> <before> <after> :flags <flags> :limit <limit> :backup <backup>)
Equivalent to
sed -i<backup> -r -e "<limit> s/<before>/<after>/<flags>g <filename>"
Limits max output line to 10000.
