| bytes | Package bytes implements functions for the manipulation of byte slices. |
| context | Package context defines the Context type, which carries deadlines, cancellation signals, and other request-scoped values across API boundaries and between processes. |
| crypto/sha256 | Package sha256 implements the SHA224 and SHA256 hash algorithms as defined in FIPS 180-4. |
| encoding/hex | Package hex implements hexadecimal encoding and decoding. |
| fmt | Package fmt implements formatted I/O with functions analogous to C's printf and scanf. |
| github.com/containerd/continuity/driver | |
| github.com/containerd/log | Package log provides types and functions related to logging, passing loggers through a context, and attaching context to the logger. |
| github.com/docker/docker/api/types/backend | Package backend includes types to send information to server backends. |
| github.com/docker/docker/builder | Package builder defines interfaces for any Docker builder to implement. |
| github.com/docker/docker/builder/remotecontext/git | |
| github.com/docker/docker/builder/remotecontext/urlutil | Package urlutil provides helper function to check if a given build-context location should be considered a URL or a remote Git repository. |
| github.com/docker/docker/errdefs | Package errdefs defines a set of error interfaces that packages should use for communicating classes of errors. |
| github.com/docker/docker/pkg/archive | Package archive provides helper functions for dealing with archive files. |
| github.com/docker/docker/pkg/chrootarchive | |
| github.com/docker/docker/pkg/ioutils | |
| github.com/docker/docker/pkg/longpath | Package longpath introduces some constants and helper functions for handling long paths in Windows. |
| github.com/docker/docker/pkg/pools | Package pools provides a collection of pools which provide various data types with buffers. |
| github.com/docker/docker/pkg/system | |
| github.com/docker/docker/pkg/tarsum | Package tarsum provides algorithms to perform checksum calculation on filesystem layers. |
| github.com/moby/buildkit/frontend/dockerfile/parser | The parser package implements a parser that transforms a raw byte-stream into a low-level Abstract Syntax Tree. |
| github.com/moby/patternmatcher | |
| github.com/moby/patternmatcher/ignorefile | |
| github.com/moby/sys/symlink | Package symlink implements FollowSymlinkInScope which is an extension of path/filepath.EvalSymlinks, as well as a Windows long-path aware version of path/filepath.EvalSymlinks from the Go standard library. |
| github.com/pkg/errors | Package errors provides simple error handling primitives. |
| hash | Package hash provides interfaces for hash functions. |
| io | Package io provides basic interfaces to I/O primitives. |
| mime | Package mime implements parts of the MIME spec. |
| net | Package net provides a portable interface for network I/O, including TCP/IP, UDP, domain name resolution, and Unix domain sockets. |
| net/http | Package http provides HTTP client and server implementations. |
| net/url | Package url parses URLs and implements query escaping. |
| os | Package os provides a platform-independent interface to operating system functionality. |
| path/filepath | Package filepath implements utility routines for manipulating filename paths in a way compatible with the target operating system-defined file paths. |
| regexp | Package regexp implements regular expression search. |
| runtime | Package runtime contains operations that interact with Go's runtime system, such as functions to control goroutines. |
| strings | Package strings implements simple functions to manipulate UTF-8 encoded strings. |
