Description

While I'm working on the oo- script for parsing the cartridge manifest, I discovered that the haproxy grep/sed/tr magic could be replaced by a bash function in the OpenShift Bash SDK:
function primary_cart_manifest {
ruby -ryaml -e "p YAML.load_file('$OPENSHIFT_PRIMARY_CARTRIDGE_DIR/metadata/manifest.yml')$1"
}
Then you can call this function using:
first_ip_in_manifest=$(primary_cart_manifest "['Endpoints'].first['Private-IP-Name']")
If you look at v2_cart_model.rb 'primary_cartridge' method, this function is not very different
as what the method is doing.
The difficulty I have with creating the oo- script for manifest parsing is the YAML format
of the manifest... You need to deal with things like Array's and Hash'es, so the syntax
could be pretty wild:
$ oo-cartridge-manifest -c 52398bc711fae092a1000007 primary -n 'Private-IP-Name' --endpoint 1
The same applies for other properties in manifest.yaml (--compatible-versions, etc..) Basically
the oo- script will need to map the YAML keys into 'options', which might turn into maintenance
nightmare ;-)
What do you guys think?
Commit pushed to master at https://github.com/openshift/origin-server https://github.com/openshift/origin-server/commit/086363bdce6736849064e3a683ca1294a9fdec34 Bug 1007455 - Added primary_cartridge methods to Ruby SDK It's fixed, verified on devenv_3821, please refer to the following results:
1. Create a scaled app
rhc app create cpl0s0 perl-5.1 -s --no-git
2. SSH into this app
rhc ssh cpl0s0
3. Check scripts code
grep -e first_ip_in_manifest -e first_port_in_manifest haproxy/hooks/set-proxy
4. Check the primary endpoint variables
env |grep PERL
at step 3:
first_ip_in_manifest=$(primary_cartridge_private_ip_name)
prim_cart_ip="OPENSHIFT_${prim_cart}_${first_ip_in_manifest}"
first_port_in_manifest=$(primary_cartridge_private_port_name)
prim_cart_port="OPENSHIFT_${prim_cart}_${first_port_in_manifest}"
