Types

type Cluster 

type Cluster struct {
	*k8s.K8s
}

Cluster is a wrapper for the k8s package that provides Zarf-specific cluster management functions.

func NewCluster 

func NewCluster() (*Cluster, error)

NewCluster creates a new Cluster instance and validates connection to the cluster by fetching the Kubernetes version.

func NewClusterOrDie 

func NewClusterOrDie() *Cluster

NewClusterOrDie creates a new Cluster instance and waits up to 30 seconds for the cluster to be ready or throws a fatal error.

func NewClusterWithWait 

func NewClusterWithWait(timeout time.Duration) (*Cluster, error)

NewClusterWithWait creates a new Cluster instance and waits for the given timeout for the cluster to be ready.

func (*Cluster) Connect added in v0.30.0 

func (c *Cluster) Connect(target string) (*k8s.Tunnel, error)

Connect will establish a tunnel to the specified target.

func (*Cluster) ConnectToZarfRegistryEndpoint added in v0.30.0 

func (c *Cluster) ConnectToZarfRegistryEndpoint(registryInfo types.RegistryInfo) (string, *k8s.Tunnel, error)

ConnectToZarfRegistryEndpoint determines if a registry endpoint is in cluster, and if so opens a tunnel to connect to it

func (*Cluster) ConnectTunnelInfo added in v0.30.0 

func (c *Cluster) ConnectTunnelInfo(zt TunnelInfo) (*k8s.Tunnel, error)

ConnectTunnelInfo connects to the cluster with the provided TunnelInfo

func (*Cluster) DeleteZarfNamespace 

func (c *Cluster) DeleteZarfNamespace()

DeleteZarfNamespace deletes the Zarf namespace from the connected cluster.

func (*Cluster) DisableRegHPAScaleDown added in v0.24.0 

func (c *Cluster) DisableRegHPAScaleDown() error

DisableRegHPAScaleDown disables the HPA scale down for the Zarf Registry.

func (*Cluster) EnableRegHPAScaleDown added in v0.24.0 

func (c *Cluster) EnableRegHPAScaleDown() error

EnableRegHPAScaleDown enables the HPA scale down for the Zarf Registry.

func (*Cluster) GenerateGitPullCreds added in v0.29.0 

func (c *Cluster) GenerateGitPullCreds(namespace, name string, gitServerInfo types.GitServerInfo) *corev1.Secret

GenerateGitPullCreds generates a secret containing the git credentials.

func (*Cluster) GenerateRegistryPullCreds 

func (c *Cluster) GenerateRegistryPullCreds(namespace, name string, registryInfo types.RegistryInfo) *corev1.Secret

GenerateRegistryPullCreds generates a secret containing the registry credentials.

func (*Cluster) GetDeployedPackage added in v0.26.0 

func (c *Cluster) GetDeployedPackage(packageName string) (deployedPackage *types.DeployedPackage, err error)

GetDeployedPackage gets the metadata information about the package name provided (if it exists in the cluster). We determine what packages have been deployed to the cluster by looking for specific secrets in the Zarf namespace.

func (*Cluster) GetDeployedZarfPackages 

func (c *Cluster) GetDeployedZarfPackages() ([]types.DeployedPackage, []error)

GetDeployedZarfPackages gets metadata information about packages that have been deployed to the cluster. We determine what packages have been deployed to the cluster by looking for specific secrets in the Zarf namespace. Returns a list of DeployedPackage structs and a list of errors.

func (*Cluster) GetInstalledChartsForComponent added in v0.30.0 

func (c *Cluster) GetInstalledChartsForComponent(packageName string, component types.ZarfComponent) (installedCharts []types.InstalledChart, err error)

GetInstalledChartsForComponent returns any installed Helm Charts for the provided package component.

func (*Cluster) HandleDataInjection 

func (c *Cluster) HandleDataInjection(wg *sync.WaitGroup, data types.ZarfDataInjection, componentPath *layout.ComponentPaths, dataIdx int)

HandleDataInjection waits for the target pod(s) to come up and inject the data into them todo: this currently requires kubectl but we should have enough k8s work to make this native now.

func (*Cluster) InitZarfState 

func (c *Cluster) InitZarfState(initOptions types.ZarfInitOptions) error

InitZarfState initializes the Zarf state with the given temporary directory and init configs.

func (*Cluster) LoadZarfState 

func (c *Cluster) LoadZarfState() (state *types.ZarfState, err error)

LoadZarfState returns the current zarf/zarf-state secret data or an empty ZarfState.

func (*Cluster) MergeZarfState added in v0.29.0 

func (c *Cluster) MergeZarfState(oldState *types.ZarfState, initOptions types.ZarfInitOptions, services []string) *types.ZarfState

MergeZarfState merges init options for provided services into the provided state to create a new state struct

func (*Cluster) PackageSecretNeedsWait added in v0.30.0 

func (c *Cluster) PackageSecretNeedsWait(deployedPackage *types.DeployedPackage, component types.ZarfComponent, skipWebhooks bool) (needsWait bool, waitSeconds int, hookName string)

PackageSecretNeedsWait checks if a package component has a running webhook that needs to be waited on.

func (*Cluster) PrintConnectTable 

func (c *Cluster) PrintConnectTable() error

PrintConnectTable will print a table of all Zarf connect matches found in the cluster.

func (*Cluster) RecordPackageDeployment 

func (c *Cluster) RecordPackageDeployment(pkg types.ZarfPackage, components []types.DeployedComponent, connectStrings types.ConnectStrings, generation int) (deployedPackage *types.DeployedPackage, err error)

RecordPackageDeployment saves metadata about a package that has been deployed to the cluster.

func (*Cluster) RecordPackageDeploymentAndWait added in v0.30.0 

func (c *Cluster) RecordPackageDeploymentAndWait(pkg types.ZarfPackage, components []types.DeployedComponent, connectStrings types.ConnectStrings, generation int, component types.ZarfComponent, skipWebhooks bool) (deployedPackage *types.DeployedPackage, err error)

RecordPackageDeploymentAndWait records the deployment of a package to the cluster and waits for any webhooks to complete.

func (*Cluster) SaveZarfState 

func (c *Cluster) SaveZarfState(state *types.ZarfState) error

SaveZarfState takes a given state and persists it to the Zarf/zarf-state secret.

func (*Cluster) StartInjectionMadness added in v0.24.0 

func (c *Cluster) StartInjectionMadness(tmpDir string, imagesDir string, injectorSeedSrcs []string)
