UNIX system administration in Common Lisp
|Disk usage||0.00 kB|
Adams is a UNIX system administration tool written in Common Lisp.
You describe your systems (hosts) using resources having properties.
The properties are then probed and synchronized by Adams using only
/bin/sh on the remote host, and
/usr/bin/ssh on the control host.
Check out https://github.com/kmx-io/kmx-io/ for a detailed example of Adams usage.
Adams is currently able to use a local shell or connect to remote hosts via ssh.
Adams is this hardcore hacker using only
bash suitable shells for adams as they are
Supported resource types :
You should only allow Adams what you would allow your system operators :
All commands issued to the remote hosts can be logged.
Adams does not grant the hosts access to its workstation while it works. Adams does not grant access to data belonging to any host. Adams does not send any data that is not of direct concern to the host. In short, all UNIX permissions are respected, Adams is a regular UNIX user.
$ sbcl --eval '(repo:install :adams)'
$ cd ~/common-lisp/cl-adams/adams $ make $ sudo cp build/adams /usr/local/bin/adams
~/.emacs file :
;; Adams (add-to-list 'auto-mode-alist '("\\.adams\\'" . lisp-mode))
tutorial.adams file :
#!/usr/local/bin/adams --script (resource 'host "adams.kmx.io" :user "adams" (resource 'user "adams" :shell "/bin/sh" :ensure :present)) (with-host "adams.kmx.io" (sync *host*))
$ chmod 755 tutorial.adams $ ./tutorial.adams
tutorial.adams script will synchronize the host “adams.kmx.io”
according to the resource specifications given in the file.
user/dx.adams file :
;; Thomas de Grivel (kmx.io) (resource 'group "dx" :gid 19256 :ensure :present) (resource 'user "dx" :uid 19256 :gid 19256 :home "/home/dx" :ensure :present)
In your main script :
#!/usr/local/bin/adams --script (resource 'host "adams.kmx.io" :user "adams" (resource 'user "adams" :shell "/bin/sh" :ensure :present) #.(include "user/dx")) (with-host "adams.kmx.io" (sync *host*))
