### OCI Runtime Specification
containerd fully supports the OCI runtime specification for running containers. We have built in functions to help you generate runtime specifications based on images as well as custom parameters.
```go
spec, err := containerd.GenerateSpec(containerd.WithImageConfig(context, image))
```
### Containers
In containerd, a container is a metadata object. Resources such as an OCI runtime specification, image, root filesystem, and other metadata can be attached to a container.
```go
redis, err := client.NewContainer(context, "redis-master",
containerd.WithSpec(spec),
)
redis, err := client.NewContainer(context, "redis-master")
defer redis.Delete(context)
```
### OCI Runtime Specification
containerd fully supports the OCI runtime specification for running containers. We have built in functions to help you generate runtime specifications based on images as well as custom parameters.
You can specify options when creating a container about how to modify the specification.
```go
redis, err := client.NewContainer(context, "redis-master", containerd.WithNewSpec(containerd.WithImageConfig(image)))
```
## Root Filesystems
containerd allows you to use overlay or snapshot filesystems with your containers. It comes with builtin support for overlayfs and btrfs.

// Package platforms provides a toolkit for normalizing, matching and
// specifying container platforms.
//
// Centered around OCI platform specifications, we define a string-based
// specifier syntax that can be used for user input. With a specifier, users
// only need to specify the parts of the platform that are relevant to their
// context, providing an operating system or architecture or both.
//
// How do I use this package?
//
// The vast majority of use cases should simply use the match function with
// user input. The first step is to parse a specifier into a matcher:
//
// m, err := Parse("linux")
// if err != nil { ... }
//
// Once you have a matcher, use it to match against the platform declared by a
// component, typically from an image or runtime. Since extracting an images
// platform is a little more involved, we'll use an example against the
// platform default:
//
// if ok := m.Match(Default()); !ok { /* doesn't match */ }
//
// This can be composed in loops for resolving runtimes or used as a filter for
// fetch and select images.
//
// More details of the specifier syntax and platform spec follow.
//
// Declaring Platform Support
//
// Components that have strict platform requirements should use the OCI
// platform specification to declare their support. Typically, this will be
// images and runtimes that should make these declaring which platform they
// support specifically. This looks roughly as follows:
//
// type Platform struct {
// Architecture string
// OS string
// Variant string
// }
//
// Most images and runtimes should at least set Architecture and OS, according
// to their GOARCH and GOOS values, respectively (follow the OCI image
// specification when in doubt). ARM should set variant under certain
// discussions, which are outlined below.
//
// Platform Specifiers
//
// While the OCI platform specifications provide a tool for components to
// specify structured information, user input typically doesn't need the full
// context and much can be inferred. To solve this problem, we introduced
// "specifiers". A specifier has the format
// `<os>|<arch>|<os>/<arch>[/<variant>]`. The user can provide either the
// operating system or the architecture or both.
//
// An example of a common specifier is `linux/amd64`. If the host has a default
// of runtime that matches this, the user can simply provide the component that
// matters. For example, if a image provides amd64 and arm64 support, the
// operating system, `linux` can be inferred, so they only have to provide
// `arm64` or `amd64`. Similar behavior is implemented for operating systems,
// where the architecture may be known but a runtime may support images from
// different operating systems.
//
// Normalization
//
// Because not all users are familiar with the way the Go runtime represents
// platforms, several normalizations have been provided to make this package
// easier to user.
//
// The following are performed for architectures:
//
// Value Normalized
// aarch64 arm64
// armhf arm
// armel arm/v6
// i386 386
// x86_64 amd64
// x86-64 amd64
//
// We also normalize the operating system `macos` to `darwin`.
//
// ARM Support
//
// To qualify ARM architecture, the Variant field is used to qualify the arm
// version. The most common arm version, v7, is represented without the variant
// unless it is explicitly provided. This is treated as equivalent to armhf. A
// previous architecture, armel, will be normalized to arm/v6.
//
// While these normalizations are provided, their support on arm platforms has
// not yet been fully implemented and tested.
