If TCP is passed in as the protocol, by default, we add TCP as the
protocol within the Kubernetes or OpenShift artifacts.
By default, TCP is already selected within Kubernetes and thus having
the TCP output is redundant.
This commit checks to see if TCP has already been selected, and if it
has, ignores adding it to the list of ports.
Closes https://github.com/kubernetes-incubator/kompose/issues/392
This adds supports for stdin_open: bool and
tty: bool support for kubernetes and openshift
providers in kompose. This maps to the
template.Spec.Containers[0].Stdin and
template.Spec.Containers[0].TTY in Kubernets
world.
Also, added tests.
Fixes#344
