Environment Variables in Kubernetes

salilpune1 · August 19, 2020, 4:39pm

@rahul456 @mmumshad , HI I feel there are couple of issues with below line:
echo -en ‘/n’

this is how its getting printed:
kubectl logs envars-fieldref -n fieldref-namespace
-en /n
node01
envars-fieldref
fieldref-namespace
10.44.0.1
default

As you can see, getting “-en /n” string in the output

If I just keep echo ‘\n’; in the args, we get correct new line character in the output:

thor@jump_host ~$ kubectl logs envars-fieldref -n fieldref-namespace

node01
envars-fieldref
fieldref-namespace
10.44.0.1
default

hi @nithyaks, as per question, your image should be ‘httpd’ instead of ‘redis’

nithyaks · August 27, 2020, 10:56am

@rahul456
