## What is a Container

Containers (mainly Linux containers) are a very **lightweight** way to package applications including all their dependencies and necessary files while keeping them isolated from other containers (other applications or components) in the same system.

  // If this field is empty then this NetworkPolicy does not allow any traffic
  // (and serves solely to ensure that the pods it selects are isolated by default).

  // List of egress rules to be applied to the selected pods. Outgoing traffic is

# Virtual Environments

When you work in Python projects you probably should use a **virtual environment** (or a similar mechanism) to isolate the packages you install for each project.

/// info

If you already know about virtual environments, how to create them and use them, you might want to skip this section. 🤓

///

/// tip

A **virtual environment** is different than an **environment variable**.

    metadata:
      name: default-deny
    spec:
      podSelector:
    ```

	This will ensure that Pods that aren't matched by any other NetworkPolicy will continue to be fully-isolated, as they were in v1beta1.

	registerBucketLevelFunc(bucketRouter, api, apiFunctions...)
}

// Takes in Erasure object layer, and the list of API end points to be tested/required, registers the API end points and returns the HTTP handler.
// Need isolated registration of API end points while writing unit tests for end points.
// All the API end points are registered only for the default case.

- Adds FQDN addressType support for EndpointSlice. ([#84091](https://github.com/kubernetes/kubernetes/pull/84091), [@robscott](https://github.com/robscott))
- Fix incorrect network policy description suggesting that pods are isolated when a network policy has no rules of a given type ([#84194](https://github.com/kubernetes/kubernetes/pull/84194), [@jackkleeman](https://github.com/jackkleeman))

	the beta1 API.
	The `net.beta.kubernetes.io/network-policy` annotation on Namespaces
	to opt in to isolation has been removed. Instead, isolation is now
	determined at a per-pod level, with pods being isolated if there is
	any NetworkPolicy whose spec.podSelector targets them. Pods that are
	targeted by NetworkPolicies accept traffic that is accepted by any of
	the NetworkPolicies (and nothing else), and pods that are not targeted

* The pod annotation `security.alpha.kubernetes.io/sysctls` now allows customization of namespaced and well isolated kernel parameters (sysctls), starting with `kernel.shm_rmid_forced`, `net.ipv4.ip_local_port_range` and `net.ipv4.tcp_syncookies` for Kubernetes 1.4.

- Pod will not start when Init container was OOM killed. ([#104650](https://github.com/kubernetes/kubernetes/pull/104650), [@yxxhero](https://github.com/yxxhero)) [SIG Node]
- PodResources interface was changed, now it returns only isolated CPUs ([#97415](https://github.com/kubernetes/kubernetes/pull/97415), [@AlexeyPerevalov](https://github.com/AlexeyPerevalov))
