Functions

func OpenFileMock 

func OpenFileMock(name string) (io.ReadCloser, error)

Types

type DockerExecConfig added in v1.40.0 

type DockerExecConfig struct {
	// Image is the fully qualified docker image name that is passed to docker for this tool.
	Image string
	// Workspace is the (optional) directory to which the current working directory is mapped
	// within the docker container.
	Workspace string
}

DockerExecConfig is the configuration for an individual tool that shall be executed in docker.

type DockerExecRunner added in v1.40.0 

type DockerExecRunner struct {
	// Runner is the ExecRunner to which all executions are forwarded in the end.
	Runner baseRunner
	// contains filtered or unexported fields
}

DockerExecRunner can be used "in place" of another ExecRunner in order to transparently execute commands within a docker container. One use-case is to test locally with tools that are not available on the current platform. When entering the run*() function of a step implementation, a DockerExecRunner can be wrapped around a command.Command{} an be configured to run certain executables within docker.

func (*DockerExecRunner) AddExecConfig added in v1.40.0 

func (d *DockerExecRunner) AddExecConfig(executable string, config DockerExecConfig) error

AddExecConfig needs to be called to store a configuration for a specific executable, in order to run this executable within docker.

func (*DockerExecRunner) RunExecutable added in v1.40.0 

func (d *DockerExecRunner) RunExecutable(executable string, parameters ...string) error

RunExecutable runs the provided executable within docker, if a DockerExecConfig has been previously associated with this executable via AddExecConfig(). Otherwise runs it directly. The BaseRunner is used for execution in any case.

Example 
package main

import (
	"bytes"
	"fmt"
	"github.com/SAP/jenkins-library/pkg/command"
	"github.com/SAP/jenkins-library/pkg/mock"

type ExecRunner interface {
	SetDir(d string)
	SetEnv(e []string)
	Stdout(out io.Writer)
	Stderr(err io.Writer)
	RunExecutable(e string, p ...string) error
}

func getMavenVersion(runner ExecRunner) (string, error) {
	output := bytes.Buffer{}
	runner.Stdout(&output)
	err := runner.RunExecutable("mvn", "--version")
	if err != nil {
		return "", fmt.Errorf("failed to run maven: %w", err)
	}
	logLines := strings.Split(output.String(), "\n")
	if len(logLines) < 1 {
		return "", fmt.Errorf("failed to obtain maven output")
	}
	return logLines[0], nil
}

func main() {
	// getMavenVersion(runner ExecRunner) executes the command "mvn --version"
	// and returns the command output as string
	runner := command.Command{}
	localMavenVersion, _ := getMavenVersion(&runner)

	dockerRunner := mock.DockerExecRunner{Runner: &runner}
	_ = dockerRunner.AddExecConfig("mvn", mock.DockerExecConfig{
		Image: "maven:3.6.1-jdk-8",
	})

	dockerMavenVersion, _ := getMavenVersion(&dockerRunner)

	fmt.Printf("Your local mvn version is %v, while the version in docker is %v", localMavenVersion, dockerMavenVersion)
}
