Types

type APIClient 

type APIClient struct {
	PfsAPIClient
	PpsAPIClient
	ObjectAPIClient
	AuthAPIClient
	DeployAPIClient
	VersionAPIClient
	AdminAPIClient
	DebugClient
	Enterprise enterprise.APIClient // not embedded--method name conflicts with AuthAPIClient
	// contains filtered or unexported fields
}

An APIClient is a wrapper around pfs, pps and block APIClients.

func NewFromAddress 

func NewFromAddress(addr string, options ...Option) (*APIClient, error)

NewFromAddress constructs a new APIClient for the server at addr.

func NewInCluster 

func NewInCluster(options ...Option) (*APIClient, error)

NewInCluster constructs a new APIClient using env vars that Kubernetes creates. This should be used to access Pachyderm from within a Kubernetes cluster with Pachyderm running on it.

func NewOnUserMachine added in v1.5.0 

func NewOnUserMachine(reportMetrics bool, prefix string, options ...Option) (*APIClient, error)

NewOnUserMachine constructs a new APIClient using env vars that may be set on a user's machine (i.e. ADDRESS), as well as $HOME/.pachyderm/config if it exists. This is primarily intended to be used with the pachctl binary, but may also be useful in tests.

TODO(msteffen) this logic is fairly linux/unix specific, and makes the pachyderm client library incompatible with Windows. We may want to move this (and similar) logic into src/server and have it call a NewFromOptions() constructor.

func (*APIClient) AddMetadata added in v1.5.1 

func (c *APIClient) AddMetadata(ctx context.Context) context.Context

AddMetadata adds necessary metadata (including authentication credentials) to the context 'ctx', preserving any metadata that is present in either the incoming or outgoing metadata of 'ctx'.

func (c *APIClient) Close() error

Close the connection to gRPC

func (APIClient) Compact added in v1.3.9 

func (c APIClient) Compact() error

func (APIClient) CreateJob 

func (c APIClient) CreateJob(pipeline string, outputCommit *pfs.Commit) (*pps.Job, error)

CreateJob creates and runs a job in PPS. This function is mostly useful internally, users should generally run work by creating pipelines as well.

func (APIClient) CreatePipeline 

func (c APIClient) CreatePipeline(
	name string,
	image string,
	cmd []string,
	stdin []string,
	parallelismSpec *pps.ParallelismSpec,
	input *pps.Input,
	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 available resources. input 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) CreatePipelineService added in v1.6.0 

func (c APIClient) CreatePipelineService(
	name string,
	image string,

	externalPort int32,
) error

CreatePipelineService creates a new pipeline service.

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 separate Repos for logs, metrics, database dumps etc.

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

func (c APIClient) DeleteJob(jobID string) error

DeleteJob deletes a job.

func (APIClient) DeletePipeline

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) DiffFile added in v1.4.8 

func (c APIClient) DiffFile(newRepoName, newCommitID, newPath, oldRepoName,
	oldCommitID, oldPath string, shallow bool) ([]*pfs.FileInfo, []*pfs.FileInfo, 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) FlushCommitF added in v1.7.0 

func (c APIClient) FlushCommitF(commits []*pfs.Commit, toRepos []*pfs.Repo, f func(*pfs.CommitInfo) error) error

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) FlushJob added in v1.7.0 

func (c APIClient) FlushJob(commits []*pfs.Commit, toPipelines []string, f func(*pps.JobInfo) error) error

func (c APIClient) FlushJobAll(commits []*pfs.Commit, toPipelines []string) ([]*pps.JobInfo, error)

FlushJobAll returns all the jobs which were triggered by commits. If toPipelines is non-nil then only the jobs between commits and those pipelines in the DAG will be returned.

func (APIClient) GarbageCollect added in v1.4.7 

func (c APIClient) GarbageCollect(memoryBytes int64) error

GarbageCollect garbage collects unused data. Currently GC needs to be run while no data is being added or removed (which, among other things, implies that there shouldn't be jobs actively running). Pfs Garbage collection uses bloom filters to keep track of live objects because it can store more objects than can be indexed in memory. This means that there is a chance for unreferenced objects to not be GCed, this chance increases as the number of objects in the system increases. You can tradeoff using more memory to get a lower chance of collisions, the default value is 10 MB and collisions should be unlikely until you have 10 million objects.

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.

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.
