Types

type APIClient 

type APIClient struct {
	PfsAPIClient
	PpsAPIClient
	ObjectAPIClient
	AuthAPIClient
	// contains filtered or unexported fields
}

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

func NewFromAddress 

func NewFromAddress(addr string) (*APIClient, error)

NewFromAddress constructs a new APIClient for the server at addr.

func NewFromAddressWithConcurrency added in v1.3.6 

func NewFromAddressWithConcurrency(addr string, maxConcurrentStreams uint) (*APIClient, error)

NewFromAddressWithConcurrency constructs a new APIClient and sets the max concurrency of streaming requests (GetFile / PutFile)

func NewInCluster 

func NewInCluster() (*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) (*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 NewOnUserMachineWithConcurrency added in v1.5.0 

func NewOnUserMachineWithConcurrency(reportMetrics bool, prefix string, maxConcurrentStreams uint) (*APIClient, error)

NewOnUserMachineWithConcurrency is identical to NewOnUserMachine, but explicitly sets a limit on the number of RPC streams that may be open simultaneously

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'

func (*APIClient) Close added in v1.2.0 

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(
	image string,
	cmd []string,
	stdin []string,
	parallelismSpec *pps.ParallelismSpec,
	input *pps.Input,
	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. input 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,

	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. 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) 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) DeleteBranch added in v1.3.19 

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

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) DiffFile added in v1.4.8 

func (c APIClient) DiffFile(newRepoName, newCommitID, newPath, oldRepoName,
	oldCommitID, oldPath string, shallow bool) ([]*pfs.FileInfo, []*pfs.FileInfo, error)

DiffFile return 2 values (unless it returns an error) the first value is files present under new path, the second is files present under old path, files which are under both paths and have identical content are omitted.

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) GarbageCollect added in v1.4.7 

func (c APIClient) GarbageCollect() 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).

func (*APIClient) GetAddress added in v1.5.0 

func (c *APIClient) GetAddress() string

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,
	master bool,
) *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'

func (APIClient) RestartDatum added in v1.4.4 

func (c APIClient) RestartDatum(jobID string, datumFilter []string) error

RestartDatum restarts a datum that's being processed as part of a job. datumFilter is a slice of strings which are matched against either the Path or Hash of the datum, the order of the strings in datumFilter is irrelevant.

func (*APIClient) SetAuthToken added in v1.5.1 

func (c *APIClient) SetAuthToken(token string)

SetAuthToken sets the authentication token that will be used for all API calls for this client.

func (APIClient) SetBranch added in v1.3.19 

func (c APIClient) SetBranch(repoName string, commit string, branch string) error

SetBranch sets a commit and its ancestors as a branch

func (APIClient) SetMaxConcurrentStreams added in v1.3.15 

func (c APIClient) SetMaxConcurrentStreams(n int)

SetMaxConcurrentStreams Sets the maximum number of concurrent streams the client can have. It is not safe to call this operations while operations are outstanding.

func (APIClient) StartCommit 

func (c APIClient) StartCommit(repoName string, branch string) (*pfs.Commit, error)

StartCommit 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.

func (APIClient) StartCommitParent added in v1.3.19 

func (c APIClient) StartCommitParent(repoName string, branch string, parentCommit string) (*pfs.Commit, error)

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 

func (c APIClient) StartPipeline(name string) error

StartPipeline restarts a stopped pipeline.

func (c APIClient) SubscribeCommit(repo string, branch string, from string) (CommitInfoIterator, error)

SubscribeCommit is like ListCommit but it keeps listening for commits as they come in.

func (APIClient) TagObject added in v1.3.9 

func (c APIClient) TagObject(hash string, tags ...string) error

TagObject applies a tag to an existing object.

func (APIClient) Walk added in v1.3.2 

func (c APIClient) Walk(repoName string, commitID string, path string, walkFn WalkFn) error

Walk walks the pfs filesystem rooted at path. walkFn will be called for each file found under path, this includes both regular files and directories.

func (*APIClient) WithCtx added in v1.5.1 

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

WithCtx returns a new APIClient that uses ctx for requests it sends.

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

LogsIter iterates through log messages returned from pps.GetLogs. Logs can be fetched with 'Next()'. The log message received can be examined with 'Message()', and any errors can be examined with 'Err()'.

func (*LogsIter) Err added in v1.3.19 

func (l *LogsIter) Err() error
