Types

type Cluster 

type Cluster struct {
	Kube *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 without waiting for the cluster to be ready.

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, withSpinner bool) (*Cluster, error)

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

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) GenerateRegistryPullCreds 

func (c *Cluster) GenerateRegistryPullCreds(namespace, name string) (*corev1.Secret, error)

GenerateRegistryPullCreds generates a secret containing the registry credentials.

func (*Cluster) GetDeployedPackage added in v0.26.0 

func (c *Cluster) GetDeployedPackage(packageName string) (types.DeployedPackage, 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) HandleDataInjection 

func (c *Cluster) HandleDataInjection(wg *sync.WaitGroup, data types.ZarfDataInjection, componentPath types.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() (types.ZarfState, error)

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

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) error

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

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(tempPath types.TempPaths, injectorSeedTags []string)

StartInjectionMadness initializes a Zarf injection into the cluster.

func (*Cluster) StopInjectionMadness added in v0.24.0 

func (c *Cluster) StopInjectionMadness() error

StopInjectionMadness handles cleanup once the seed registry is up.

func (*Cluster) StripZarfLabelsAndSecretsFromNamespaces 

func (c *Cluster) StripZarfLabelsAndSecretsFromNamespaces()

StripZarfLabelsAndSecretsFromNamespaces removes metadata and secrets from existing namespaces no longer manged by Zarf.

type DockerConfig 

type DockerConfig struct {
	Auths DockerConfigEntry `json:"auths"`
}

DockerConfig contains the authentication information from the machine's docker config.

type DockerConfigEntry 

type DockerConfigEntry map[string]DockerConfigEntryWithAuth

DockerConfigEntry contains a map of DockerConfigEntryWithAuth for a registry.

type DockerConfigEntryWithAuth 

type DockerConfigEntryWithAuth struct {
	Auth string `json:"auth"`
}

DockerConfigEntryWithAuth contains a docker config authentication string.

type ServiceInfo added in v0.24.0 

type ServiceInfo struct {
	Namespace string
	Name      string
	Port      int
}

ServiceInfo contains information necessary for connecting to a cluster service.

func ServiceInfoFromNodePortURL added in v0.24.0 

func ServiceInfoFromNodePortURL(nodePortURL string) (*ServiceInfo, error)

ServiceInfoFromNodePortURL takes a nodePortURL and parses it to find the service info for connecting to the cluster. The string is expected to follow the following format: Example nodePortURL: 127.0.0.1:{PORT}.

func ServiceInfoFromServiceURL added in v0.24.0 

func ServiceInfoFromServiceURL(serviceURL string) (*ServiceInfo, error)

ServiceInfoFromServiceURL takes a serviceURL and parses it to find the service info for connecting to the cluster. The string is expected to follow the following format: Example serviceURL: http://{SERVICE_NAME}.{NAMESPACE}.svc.cluster.local:{PORT}.

type Tunnel 

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

Tunnel is the main struct that configures and manages port forwarding tunnels to Kubernetes resources.

func NewTunnel 

func NewTunnel(namespace, resourceType, resourceName string, local, remote int) (*Tunnel, error)

NewTunnel will create a new Tunnel struct. Note that if you use 0 for the local port, an open port on the host system will be selected automatically, and the Tunnel struct will be updated with the selected port.

func NewZarfTunnel 

func NewZarfTunnel() (*Tunnel, error)

NewZarfTunnel will create a new Tunnel struct for the Zarf namespace.

func (*Tunnel) AddSpinner 

func (tunnel *Tunnel) AddSpinner(spinner *message.Spinner)

AddSpinner will add a spinner to the tunnel to show progress.

func (*Tunnel) Close 

func (tunnel *Tunnel) Close()

Close disconnects a tunnel connection by closing the StopChan, thereby stopping the goroutine.

func (tunnel *Tunnel) Connect(target string, blocking bool) error

Connect will establish a tunnel to the specified target.

func (*Tunnel) EnableAutoOpen 

func (tunnel *Tunnel) EnableAutoOpen()

func (*Tunnel) Endpoint 

func (tunnel *Tunnel) Endpoint() string

Endpoint returns the tunnel ip address and port (i.e. for docker registries)

func (*Tunnel) FullURL added in v0.26.3 

func (tunnel *Tunnel) FullURL() string

FullURL returns the tunnel endpoint as a HTTP URL string with the urlSuffix appended.

func (*Tunnel) HTTPEndpoint added in v0.23.2 

func (tunnel *Tunnel) HTTPEndpoint() string

HTTPEndpoint returns the tunnel endpoint as a HTTP URL string.
