I am trying to auto generate my host file for a grid deployment.
The following works well if I actually put a number in the of the for
loop. I have tried quite a few variations on this theme but cannot seem
to identify a working solution. Any ideas?
b_grid=$grid
let b_grid_size=$grid_size
let b_final_oct=$first_grid_node_final_oct
let b_grid_size=$grid_size
b_pub_sub_net=$pub_sub_net
b_priv_sub_net=$priv_sub_net
I'm not sure I grok the "let" stuff, but if the issue is you have a
variable stored in Cobbler as a string and you want the Python range
function to work, that should be easy enough.
Try something simple to cast the string back into an int and range
should work fine.
#set $mysize = int($mysize)
In general, more of a Cheetah question, so you may also like to see
cheetahtemplate.org for other docs/info.

#for $cur_node in $range( $b_grid_size )
let b_vip=$b_final_oct+20
awk -v pub_sub_net="$b_pub_sub_net" -v cur_oct="$b_final_oct" -v
grid="$b_grid" -v cur_node="$cur_node" 'BEGIN {printf("%s%s
%s%02s.%s.gesi %s%02s\n", pub_sub_net, cur_oct, grid, cur_node, grid,
grid, cur_node)}' >> /etc/hosts
awk -v pub_sub_net="$b_pub_sub_net" -v grid="$b_grid" -v
vip="$b_vip"
- -v cur_node="$cur_node" 'BEGIN {printf("%s%s %s%02s-vip\n",
pub_sub_net, vip, grid, cur_node)}' >> /etc/hosts
awk -v priv_sub_net="$b_priv_sub_net" -v grid="$b_grid" -v
cur_oct="$b_final_oct" -v cur_node="$cur_node" 'BEGIN
{printf("%s%s
%s%02s-priv\n", priv_sub_net, cur_oct, grid, cur_node)}' >> /etc/hosts
let b_final_oct+=1
#end for
