**** Unable to start the server: Error starting server : Lifecycle error: Fail to install license: Not in GZIP format

Cause

this is due the License needs to be in gzip format when mapping it using config file 


so if we create mapping 

for example bellow : 

apiVersion: v1

kind: ConfigMap

metadata:

  name: license

  annotations:

    description: Configuration Map for license

data:

  accept.license: "true"

  ssg.license: <we need to put value of the licesne file in gzip format here>


Now,  when we create gateway pod and we call for this license variable via   key: ssg.license it will come in in gzip format 

        env:

          - name: ACCEPT_LICENSE

            valueFrom:

              configMapKeyRef:

                name: license

                key: accept.license

          - name: EXTRA_JAVA_ARGS

            valueFrom:

              configMapKeyRef:

                name: env

                key: extra-java-args.env

          - name: SSG_LICENSE

            valueFrom:

              configMapKeyRef:

                name: license

                key: ssg.license 

Environment

Release : 10.0

Component : CA API Gateway 

Resolution

Open Licesne File copy the text format, make sure no extra lines are copied 
go to gzip tool and gzip the text 

take the text and copy into config Mapping variable for license
