Functions

func AppendEnv

func AppendEnv(a []corev1.EnvVar, b []corev1.EnvVar) []corev1.EnvVar

AppendEnv appends envs `b` into `a` ignoring envs whose names already exist in `b`. Note that this will not change relative order of envs.

func AppendEnvIfPresent

func AppendEnvIfPresent(envs []corev1.EnvVar, name string) []corev1.EnvVar

AppendEnvIfPresent appends the given environment if present

func AppendOverwriteEnv

func AppendOverwriteEnv(a []corev1.EnvVar, b []corev1.EnvVar) []corev1.EnvVar

AppendOverwriteEnv appends envs b into a and overwrites the envs whose names already exist in b. Note that this will not change relative order of envs.
