Overview

Package bindings provides golang-based access to the Podman REST API. Users can then interact with API endpoints to manage containers, images, pods, etc.

This package exposes a series of methods that allow users to firstly create their connection with the API endpoints. Once the connection is established, users can then manage the Podman container runtime.

Functions

func CheckResponseCode

func CheckResponseCode(inError error) (int, error)

func FiltersToString

func FiltersToString(filters map[string][]string) (string, error)

FiltersToString converts our typical filter format of a map[string][]string to a query/html safe string.

func JoinURL

func JoinURL(elements ...string) string

JoinURL elements with '/'

func NewConnection

func NewConnection(ctx context.Context, uri string) (context.Context, error)

func NewConnectionWithIdentity

func NewConnectionWithIdentity(ctx context.Context, uri string, identity string) (context.Context, error)

NewConnection takes a URI as a string and returns a context with the Connection embedded as a value. This context needs to be passed to each endpoint to work correctly.

A valid URI connection should be scheme:// For example tcp://localhost:<port> or unix:///run/podman/podman.sock or ssh://<user>@<host>[:port]/run/podman/podman.sock?secure=True

func (*Connection) DoRequest

func (c *Connection) DoRequest(httpBody io.Reader, httpMethod, endpoint string, queryParams url.Values, header map[string]string, pathValues ...string) (*APIResponse, error)

DoRequest assembles the http request and returns the response
