はじめに KubernetesでCI/CDができる**Tektonについてどんなものなのか**、

Tekton

Tasks Overview Configuring a Task Task vs. ClusterTask Defining Steps Reserved directories Running scripts within Steps Windows scripts Specifying a timeout Specifying onError for a step Accessing Step’s exitCode in subsequent Steps Produce a task result with onError Breakpoint on failure with onError Redirecting step output streams with stdoutConfig and stderrConfig Specifying Parameters Specifying Workspaces Emitting Results Larger Results using sidecar logs Specifying Volumes Specifying a Step template Specifying Sidecars Specifying a DisplayName Adding a description Using variable substitution Substituting parameters and resources Substituting Array parameters Substituting Workspace paths Substituting Volume names and types Substituting in Script blocks Code examples Building and pushing a Docker image Mounting multiple Volumes Mounting a ConfigMap as a Volume source Using a Secret as an environment source Using a Sidecar in a Task Debugging Inspecting the file structure Inspecting the Pod Running Step Containers as a Non Root User Task Authoring Recommendations Overview A Task is a collection of Steps that you define and arrange in a specific order of execution as part of your continuous integration flow.

TaskRuns Overview Configuring a TaskRun Specifying the target Task Tekton Bundles Remote Tasks Specifying Parameters Propagated Parameters Propagated Object Parameters Extra Parameters Specifying Resource limits Specifying Task-level ComputeResources Specifying a Pod template Specifying Workspaces Propagated Workspaces Specifying Sidecars Configuring Task Steps and Sidecars in a TaskRun Specifying LimitRange values Specifying Retries Configuring the failure timeout Specifying ServiceAccount credentials TaskRun status The status field Monitoring execution status Monitoring Steps Steps Monitoring Results Cancelling a TaskRun Debugging a TaskRun Breakpoint on Failure Debug Environment Events Running a TaskRun Hermetically Code examples Example TaskRun with a referenced Task Example TaskRun with an embedded Task Example of reusing a Task Example of Using custom ServiceAccount credentials Example of Running Step Containers as a Non Root User Overview A TaskRun allows you to instantiate and execute a Task on-cluster.

Pipelines Pipelines Overview Configuring a Pipeline Specifying Workspaces Specifying Parameters Adding Tasks to the Pipeline Specifying Display Name Specifying Remote Tasks Specifying Pipelines in PipelineTasks Specifying Parameters in PipelineTasks Specifying Matrix in PipelineTasks Specifying Workspaces in PipelineTasks Tekton Bundles Using the runAfter field Using the retries field Using the onError field Produce results with OnError Guard Task execution using when expressions Guarding a Task and its dependent Tasks Cascade when expressions to the specific dependent Tasks Compose using Pipelines in Pipelines Guarding a Task only Configuring the failure timeout Using variable substitution Using the retries and retry-count variable substitutions Using Results Passing one Task’s Results into the Parameters or when expressions of another Emitting Results from a Pipeline Configuring the Task execution order Adding a description Adding Finally to the Pipeline Specifying Display Name Specifying Workspaces in finally tasks Specifying Parameters in finally tasks Specifying matrix in finally tasks Consuming Task execution results in finally Consuming Pipeline result with finally PipelineRun Status with finally Using Execution Status of pipelineTask Using Aggregate Execution Status of All Tasks Guard finally Task execution using when expressions when expressions using Parameters in finally Tasks when expressions using Results in finally ‘Tasks` when expressions using Execution Status of PipelineTask in finally tasks when expressions using Aggregate Execution Status of Tasks in finally tasks Known Limitations Cannot configure the finally task execution order Using Custom Tasks Specifying the target Custom Task Specifying a Custom Task Spec in-line (or embedded) Specifying parameters Specifying matrix Specifying workspaces Using Results Specifying Timeout Specifying Retries Known Custom Tasks Code examples Overview A Pipeline is a collection of Tasks that you define and arrange in a specific order of execution as part of your continuous integration flow.

PipelineRuns PipelineRuns Overview Configuring a PipelineRun Specifying the target Pipeline Tekton Bundles Remote Pipelines Specifying Task-level ComputeResources Specifying Parameters Propagated Parameters Scope and Precedence Default Values Object Parameters Specifying custom ServiceAccount credentials Mapping ServiceAccount credentials to Tasks Specifying a Pod template Specifying taskRunSpecs Specifying Workspaces Propagated Workspaces Referenced TaskRuns within Embedded PipelineRuns Specifying LimitRange values Configuring a failure timeout PipelineRun status The status field Monitoring execution status Marking off user errors Cancelling a PipelineRun Gracefully cancelling a PipelineRun Gracefully stopping a PipelineRun Pending PipelineRuns Overview A PipelineRun allows you to instantiate and execute a Pipeline on-cluster.
