Functions

func AppendEnv added in v1.1.0 

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 added in v1.1.4 

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

AppendEnvIfPresent appends the given environment if present

func AppendOverwriteEnv added in v1.1.4 

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.

func BuildStorageVolumeAndVolumeMount added in v1.1.8 

func BuildStorageVolumeAndVolumeMount(storageVolumes []v1alpha1.StorageVolume, defaultStorageClassName *string, memberType v1alpha1.MemberType) ([]corev1.VolumeMount, []corev1.PersistentVolumeClaim)

  • pass the map generated by TiDB-Operator as the first argument.
  • pass components' map (labels or annotations) before cluster's.
