## Config

+------------------------------------------------------------------------------
| OC_EDITOR=vim
+------------------------------------------------------------------------------


## Download Logs

Houston logs sind NICHT im storage-manager. Musst direkt im houston pod
schauen.

Log paths:
- Storage Mgr -> "/data/logs/SVC_NAME"
- Service pod -> "/usr/local/jetty/logs".
- Houston pod -> "/usr/local/vertx/logs".

When tar fails all the time, try:  --ignore-failed-read

Templates:
+------------------------------------------------------------------------------
| oc -n NAMESPACE exec pod_name -- sh -c "echo 'gugus'"
| 
| # dload service logs via storage-manager
| oc -n NAMESPACE exec storage-manager-XXX -- sh -c "cd /data/logs/SVC_NAME && tar --ignore-failed-read -cz *.log*" > `date +SVC_NAME-STAGE-logs-%Y%m%d-%H%M%S.tgz`
| 
| # DLoad logs directly from a service pod
| oc -n NAMESPACE exec SVC_POD -- sh -c "cd /usr/local/jetty/logs && tar --ignore-failed-read --xform \"s:^:SVC_NAME-STAGE-logs-YYYYmmdd-HHMMSS/:\" -cz *.log*" > SAME_NAME_AS_BEFORE.tgz
| 
| # Download logs from HOUSTON:
| oc -n NAMESPACE exec houston-XXX -- sh -c "cd /usr/local/vertx/logs && tar -cz *" > `date -uIs +"houston-STAGE-logs-%Y%m%d-%H%M%SZ.tgz"`
| 
| # Download logs from EAGLE:
| oc -n NAMESPACE exec houston-XXX -- sh -c "cd /usr/local/vertx/logs && tar --xform \"s:^:houston-STAGE-logs-YYYYmmdd-HHMMSS-POD/:\" -cz *" > SAME_NAME_AS_BEFORE.tgz
+------------------------------------------------------------------------------


## Edit config maps

Configmaps for persistent changes are on
"https://gitit.post.ch/projects/SECINF/repos/openshift-isa"

To do direct manipulations:
+------------------------------------------------------------------------------
| oc get configmap
| oc edit configmap SVC_NAME-config
| oc describe configmaps SVC-config > SVC-config
+------------------------------------------------------------------------------


## Copy file to pod

(TODO: not tested yet)
tar -cz foo bar | oc -n NAMESPACE exec -i POD_NAME -- bash -c 'tar -C logs -zx'

HINT: ALL files from Current dir (.) will get uploaded (when global rsync not available).
+------------------------------------------------------------------------------
| oc -n NAMESPACE rsync . POD_NAME:/dst/dir --no-perms --exclude=* --include=MY_FILE.txt
+------------------------------------------------------------------------------


## Expose port
+------------------------------------------------------------------------------
| oc -n NAMESPACE expose service SVC_NAME --hostname=isa-SVC_NAME-STAGE.ospa.pnet.ch --port=1234 --name=isa-SVC_NAME-STAGE
+------------------------------------------------------------------------------


## up/down scale from cli. input von thom (20230815)
