Variables

var (
	// DefaultPushOrPullRetryCount is the number of retries of pushing or pulling the built Docker image
	// into a configured repository

Functions

func ExtractImageContent

func ExtractImageContent(ctx context.Context, dockerClient DockerClient, dir string, build *buildapi.Build) error

func ExtractInputBinary

func ExtractInputBinary(in io.Reader, source *buildapi.BinaryBuildSource, dir string) error

ExtractInputBinary processes the provided input stream as directed by BinaryBuildSource into dir.

func GetCGroupLimits

func GetCGroupLimits() (*s2iapi.CGroupLimits, error)

GetCGroupLimits returns a struct populated with cgroup limit values gathered from the local /sys/fs/cgroup filesystem. Overflow values are set to math.MaxInt64.

func GetDockerClient

func GetDockerClient() (client *docker.Client, endpoint string, err error)

GetDockerClient returns a valid Docker client, the address of the client, or an error if the client couldn't be created.

func GetSourceRevision

func GetSourceRevision(build *buildapi.Build, sourceInfo *git.SourceInfo) *buildapi.SourceRevision

GetSourceRevision returns a SourceRevision object either from the build (if it already had one) or by creating one from the sourceInfo object passed in.

func GitClone

func GitClone(ctx context.Context, gitClient GitClient, gitSource *buildapi.GitBuildSource, revision *buildapi.SourceRevision, dir string) (*git.SourceInfo, error)

GitClone clones the source associated with a build(if any) into the specified directory

func HandleBuildStatusUpdate

func HandleBuildStatusUpdate(build *buildapi.Build, client client.BuildInterface, sourceRev *buildapi.SourceRevision)

HandleBuildStatusUpdate handles updating the build status retries occur on update conflict and unreachable api server

func ManageDockerfile

func ManageDockerfile(dir string, build *buildapi.Build) error

ManageDockerfile manipulates the dockerfile for docker builds. It will write the inline dockerfile to the working directory (possibly overwriting an existing dockerfile) and then update the dockerfile in the working directory (accounting for contextdir+dockerfilepath) with new FROM image information based on the imagestream/imagetrigger and also adds some env and label values to the dockerfile based on the build information.

func MergeEnv

func MergeEnv(oldEnv, newEnv []string) []string

MergeEnv will take an existing environment and merge it with a new set of variables. For variables with the same name in both, only the one in the new environment will be kept.

func RetryImageAction

func RetryImageAction(client DockerClient, opts interface{}, authConfig docker.AuthConfiguration) error

func SafeForLoggingDockerConfig

func SafeForLoggingDockerConfig(config *docker.Config) *docker.Config

SafeForLoggingDockerConfig returns a copy of a docker config struct where any proxy credentials in the env section of the config have been redacted.

func SafeForLoggingDockerCreateOptions

func SafeForLoggingDockerCreateOptions(opts *docker.CreateContainerOptions) *docker.CreateContainerOptions

SafeForLoggingDockerCreateOptions returns a copy of a docker create container options struct where any proxy credentials in the env section of the config have been redacted.

Types

type DockerBuilder

type DockerBuilder struct {
	// contains filtered or unexported fields
}

DockerBuilder builds Docker images given a git repository URL

func NewDockerBuilder

func NewDockerBuilder(dockerClient DockerClient, buildsClient client.BuildInterface, build *buildapi.Build, cgLimits *s2iapi.CGroupLimits) *DockerBuilder

NewDockerBuilder creates a new instance of DockerBuilder

func (*DockerBuilder) Build

func (d *DockerBuilder) Build() error

Build executes a Docker build

type DockerClient

type DockerClient interface {
	AttachToContainerNonBlocking(opts docker.AttachToContainerOptions) (docker.CloseWaiter, error)
	BuildImage(opts docker.BuildImageOptions) error
	PushImage(opts docker.PushImageOptions, auth docker.AuthConfiguration) error
	RemoveImage(name string) error
	CreateContainer(opts docker.CreateContainerOptions) (*docker.Container, error)
	DownloadFromContainer(id string, opts docker.DownloadFromContainerOptions) error
	PullImage(opts docker.PullImageOptions, auth docker.AuthConfiguration) error
	RemoveContainer(opts docker.RemoveContainerOptions) error
	InspectImage(name string) (*docker.Image, error)
	StartContainer(id string, hostConfig *docker.HostConfig) error
	WaitContainer(id string) (int, error)
	Logs(opts docker.LogsOptions) error
	TagImage(name string, opts docker.TagImageOptions) error
}

DockerClient is an interface to the Docker client that contains the methods used by the common builder

type GitClient

type GitClient interface {
	CloneWithOptions(dir string, url string, args ...string) error
	Fetch(dir string, url string, ref string) error
	Checkout(dir string, ref string) error
	PotentialPRRetryAsFetch(dir string, url string, ref string, err error) error
	SubmoduleUpdate(dir string, init, recursive bool) error
	TimedListRemote(timeout time.Duration, url string, args ...string) (string, string, error)
	GetInfo(location string) (*git.SourceInfo, []error)
}

GitClient performs git operations

type KeyValue

type KeyValue struct {
	Key   string
	Value string
}

KeyValue can be used to build ordered lists of key-value pairs.

type S2IBuilder

type S2IBuilder struct {
	// contains filtered or unexported fields
}

S2IBuilder performs an STI build given the build object

func NewS2IBuilder

func NewS2IBuilder(dockerClient DockerClient, dockerSocket string, buildsClient client.BuildInterface, build *buildapi.Build,
	cgLimits *s2iapi.CGroupLimits) *S2IBuilder

NewS2IBuilder creates a new STIBuilder instance

func (*S2IBuilder) Build

func (s *S2IBuilder) Build() error

Build executes S2I build based on configured builder, S2I builder factory and S2I config validator
