func (APIClient) CreateJob 

func (c APIClient) CreateJob(
	image string,
	cmd []string,
	stdin []string,
	parallelismSpec *pps.ParallelismSpec,
	inputs []*pps.JobInput,
	internalPort int32,
	externalPort int32,
) (*pps.Job, error)

CreateJob creates and runs a job in PPS. image is the Docker image to run the job in. cmd is the command passed to the Docker run invocation. NOTE as with Docker cmd is not run inside a shell that means that things like wildcard globbing (*), pipes (|) and file redirects (> and >>) will not work. To get that behavior you should have your command be a shell of your choice and pass a shell script to stdin. stdin is a slice of lines that are sent to your command on stdin. Lines need not end in newline characters. parallelism is how many copies of your container should run in parallel. You may pass 0 for parallelism in which case PPS will set the parallelism based on availabe resources. inputs specifies a set of Commits that will be visible to the job during runtime. parentJobID specifies the a job to use as a parent, it may be left empty in which case there is no parent job. If not left empty your job will use the parent Job's output commit as the parent of its output commit.

func (APIClient) CreatePipeline 

func (c APIClient) CreatePipeline(
	name string,
	image string,
	cmd []string,
	stdin []string,
	parallelismSpec *pps.ParallelismSpec,
	inputs []*pps.PipelineInput,
	outputBranch string,
	update bool,
) error

CreatePipeline creates a new pipeline, pipelines are the main computation object in PPS they create a flow of data from a set of input Repos to an output Repo (which has the same name as the pipeline). Whenever new data is committed to one of the input repos the pipelines will create jobs to bring the output Repo up to data. image is the Docker image to run the jobs in. cmd is the command passed to the Docker run invocation. NOTE as with Docker cmd is not run inside a shell that means that things like wildcard globbing (*), pipes (|) and file redirects (> and >>) will not work. To get that behavior you should have your command be a shell of your choice and pass a shell script to stdin. stdin is a slice of lines that are sent to your command on stdin. Lines need not end in newline characters. parallelism is how many copies of your container should run in parallel. You may pass 0 for parallelism in which case PPS will set the parallelism based on availabe resources. inputs specifies a set of Repos that will be visible to the jobs during runtime. commits to these repos will cause the pipeline to create new jobs to process them. update indicates that you want to update an existing pipeline

func (APIClient) CreateRepo 

func (c APIClient) CreateRepo(repoName string) error

CreateRepo creates a new Repo object in pfs with the given name. Repos are the top level data object in pfs and should be used to store data of a similar type. For example rather than having a single Repo for an entire project you might have seperate Repos for logs, metrics, database dumps etc.

func (APIClient) DeleteAll 

func (c APIClient) DeleteAll() error

DeleteAll deletes everything in the cluster. Use with caution, there is no undo.

func (APIClient) DeleteBranch added in v1.3.19 

func (c APIClient) DeleteBranch(repoName string, branch string) error

DeleteBranch deletes a branch, but leaves the commits themselves intact. In other words, those commits can still be accessed via commit IDs and other branches they happen to be on.

func (APIClient) DeleteCommit 

func (c APIClient) DeleteCommit(repoName string, commitID string) error

DeleteCommit deletes a commit. Note it is currently not implemented.

func (APIClient) DeleteFile 

func (c APIClient) DeleteFile(repoName string, commitID string, path string) error

DeleteFile deletes a file from a Commit. DeleteFile leaves a tombstone in the Commit, assuming the file isn't written to later attempting to get the file from the finished commit will result in not found error. The file will of course remain intact in the Commit's parent.

func (APIClient) DeleteJob added in v1.3.0 

func (c APIClient) DeleteJob(jobID string) error

DeleteJob deletes a job.

func (APIClient) DeletePipeline 

func (c APIClient) DeletePipeline(name string, deleteJobs bool) error

DeletePipeline deletes a pipeline along with its output Repo.

func (APIClient) DeleteRepo 

func (c APIClient) DeleteRepo(repoName string, force bool) error

DeleteRepo deletes a repo and reclaims the storage space it was using. Note that as of 1.0 we do not reclaim the blocks that the Repo was referencing, this is because they may also be referenced by other Repos and deleting them would make those Repos inaccessible. This will be resolved in later versions. If "force" is set to true, the repo will be removed regardless of errors. This argument should be used with care.

func (APIClient) FinishCommit 

func (c APIClient) FinishCommit(repoName string, commitID string) error

FinishCommit ends the process of committing data to a Repo and persists the Commit. Once a Commit is finished the data becomes immutable and future attempts to write to it with PutFile will error.

func (APIClient) FlushCommit 

func (c APIClient) FlushCommit(commits []*pfs.Commit, toRepos []*pfs.Repo) (CommitInfoIterator, error)

FlushCommit returns an iterator that returns commits that have the specified `commits` as provenance. Note that the iterator can block if jobs have not successfully completed. This in effect waits for all of the jobs that are triggered by a set of commits to complete.

If toRepos is not nil then only the commits up to and including those repos will be considered, otherwise all repos are considered.

Note that it's never necessary to call FlushCommit to run jobs, they'll run no matter what, FlushCommit just allows you to wait for them to complete and see their output once they do.

func (APIClient) GetFile 

func (c APIClient) GetFile(repoName string, commitID string, path string, offset int64, size int64, writer io.Writer) error

GetFile returns the contents of a file at a specific Commit. offset specifies a number of bytes that should be skipped in the beginning of the file. size limits the total amount of data returned, note you will get fewer bytes than size if you pass a value larger than the size of the file. If size is set to 0 then all of the data will be returned.

func (APIClient) GetFileReader added in v1.3.19 

func (c APIClient) GetFileReader(repoName string, commitID string, path string, offset int64, size int64) (io.Reader, error)

GetFileReader returns a reader for the contents of a file at a specific Commit. offset specifies a number of bytes that should be skipped in the beginning of the file. size limits the total amount of data returned, note you will get fewer bytes than size if you pass a value larger than the size of the file. If size is set to 0 then all of the data will be returned.

func (APIClient) GetLogs 

func (c APIClient) GetLogs(
	pipelineName string,
	jobID string,
	data []string,
) *LogsIter

GetLogs gets logs from a job (logs includes stdout and stderr). 'pipelineName', 'jobID', and 'data', are all filters. To forego any filter, simply pass an empty value, though one of 'pipelineName' and 'jobID' must be set. Responses are written to 'messages'

StartCommitParent begins the process of committing data to a Repo. Once started you can write to the Commit with PutFile and when all the data has been written you must finish the Commit with FinishCommit. NOTE, data is not persisted until FinishCommit is called. branch is a more convenient way to build linear chains of commits. When a commit is started with a non empty branch the value of branch becomes an alias for the created Commit. This enables a more intuitive access pattern. When the commit is started on a branch the previous head of the branch is used as the parent of the commit. parentCommit specifies the parent Commit, upon creation the new Commit will appear identical to the parent Commit, data can safely be added to the new commit without affecting the contents of the parent Commit. You may pass "" as parentCommit in which case the new Commit will have no parent and will initially appear empty.

func (APIClient) StartPipeline added in v1.2.0
