# kubernetes_pod
A pod is a group of one or more containers, the shared storage for those containers, and options about how to run the containers. Pods are always co-located and co-scheduled, and run in a shared context.
Read more at https://kubernetes.io/docs/concepts/workloads/pods/pod/
## Example Usage
```hcl
resource "kubernetes_pod" "test" {
metadata {
name = "terraform-example"
}
spec {
container {
image = "nginx:1.7.9"

* `generate_name` - (Optional) Prefix, used by the server, to generate a unique name ONLY IF the `name` field has not been provided. This value will also be combined with a unique suffix. Read more: https://github.com/kubernetes/community/blob/master/contributors/devel/api-conventions.md#idempotency
* `labels` - (Optional) Map of string keys and values that can be used to organize and categorize (scope and select) the pod. May match selectors of replication controllers and services. More info: http://kubernetes.io/docs/user-guide/labels
* `name` - (Optional) Name of the pod, must be unique. Cannot be updated. More info: http://kubernetes.io/docs/user-guide/identifiers#names

* `self_link` - A URL representing this pod.
* `uid` - The unique in time and space value for this pod. More info: http://kubernetes.io/docs/user-guide/identifiers#uids
### `spec`
#### Arguments
* `active_deadline_seconds` - (Optional) Optional duration in seconds the pod may be active on the node relative to StartTime before the system will actively try to mark it failed and kill associated containers. Value must be a positive integer.
* `container` - (Optional) List of containers belonging to the pod. Containers cannot currently be added or removed. There must be at least one container in a Pod. Cannot be updated. More info: http://kubernetes.io/docs/user-guide/containers
* `dns_policy` - (Optional) Set DNS policy for containers within the pod. One of 'ClusterFirst' or 'Default'. Defaults to 'ClusterFirst'.
* `host_ipc` - (Optional) Use the host's ipc namespace. Optional: Default to false.

* `termination_grace_period_seconds` - (Optional) Optional duration in seconds the pod needs to terminate gracefully. May be decreased in delete request. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period will be used instead. The grace period is the duration in seconds after the processes running in the pod are sent a termination signal and the time when the processes are forcibly halted with a kill signal. Set this value longer than the expected cleanup time for your process.
* `volume` - (Optional) List of volumes that can be mounted by containers belonging to the pod. More info: http://kubernetes.io/docs/user-guide/volumes
### `container`
#### Arguments
* `args` - (Optional) Arguments to the entrypoint. The docker image's CMD is used if this is not provided. Variable references $(VAR_NAME) are expanded using the container's environment. If a variable cannot be resolved, the reference in the input string will be unchanged. The $(VAR_NAME) syntax can be escaped with a double $$, ie: $$(VAR_NAME). Escaped references will never be expanded, regardless of whether the variable exists or not. Cannot be updated. More info: http://kubernetes.io/docs/user-guide/containers#containers-and-commands
* `command` - (Optional) Entrypoint array. Not executed within a shell. The docker image's ENTRYPOINT is used if this is not provided. Variable references $(VAR_NAME) are expanded using the container's environment. If a variable cannot be resolved, the reference in the input string will be unchanged. The $(VAR_NAME) syntax can be escaped with a double $$, ie: $$(VAR_NAME). Escaped references will never be expanded, regardless of whether the variable exists or not. Cannot be updated.

* `lifecycle` - (Optional) Actions that the management system should take in response to container lifecycle events
* `liveness_probe` - (Optional) Periodic probe of container liveness. Container will be restarted if the probe fails. Cannot be updated. More info: http://kubernetes.io/docs/user-guide/pod-states#container-probes
* `name` - (Required) Name of the container specified as a DNS_LABEL. Each container in a pod must have a unique name (DNS_LABEL). Cannot be updated.
* `port` - (Optional) List of ports to expose from the container. Exposing a port here gives the system additional information about the network connections a container uses, but is primarily informational. Not specifying a port here DOES NOT prevent that port from being exposed. Any port which is listening on the default "0.0.0.0" address inside a container will be accessible from the network. Cannot be updated.
* `readiness_probe` - (Optional) Periodic probe of container service readiness. Container will be removed from service endpoints if the probe fails. Cannot be updated. More info: http://kubernetes.io/docs/user-guide/pod-states#container-probes
* `resources` - (Optional) Compute Resources required by this container. Cannot be updated. More info: http://kubernetes.io/docs/user-guide/persistent-volumes#resources
* `security_context` - (Optional) Security options the pod should run with. More info: http://releases.k8s.io/HEAD/docs/design/security_context.md
* `stdin` - (Optional) Whether this container should allocate a buffer for stdin in the container runtime. If this is not set, reads from stdin in the container will always result in EOF.
* `stdin_once` - (Optional) Whether the container runtime should close the stdin channel after it has been opened by a single attach. When stdin is true the stdin stream will remain open across multiple attach sessions. If stdinOnce is set to true, stdin is opened on container start, is empty until the first client attaches to stdin, and then remains open and accepts data until the client disconnects, at which time stdin is closed and remains closed until the container is restarted. If this flag is false, a container processes that reads from stdin will never receive an EOF.
* `termination_message_path` - (Optional) Optional: Path at which the file to which the container's termination message will be written is mounted into the container's filesystem. Message written is intended to be brief final status, such as an assertion failure message. Defaults to /dev/termination-log. Cannot be updated.
* `tty` - (Optional) Whether this container should allocate a TTY for itself
* `volume_mount` - (Optional) Pod volumes to mount into the container's filesystem. Cannot be updated.
* `working_dir` - (Optional) Container's working directory. If not specified, the container runtime's default will be used, which might be configured in the container image. Cannot be updated.
