Types ¶

type Interface ¶

type Interface interface {
	Version(context.Context) (*Version, error)
}

Interface is used to check what cert-manager version is installed

type Version ¶

type Version struct {
	// If all found versions are the same,
	// this field will contain that version
	Detected string `json:"detected,omitempty"`

	Sources map[string]string `json:"sources"`
}

type VersionChecker ¶ added in v1.7.0

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

VersionChecker implements a version checker using a controller-runtime client

func New ¶

func New(restcfg *rest.Config, scheme *runtime.Scheme) (*VersionChecker, error)

New returns a cert-manager version checker. Prefer New over NewFromClient since New will ensure the scheme is configured correctly.

func NewFromClient ¶ added in v1.7.0

func NewFromClient(cl client.Client) *VersionChecker

NewFromClient initialises a VersionChecker using the given client. Prefer New instead, which will ensure that the scheme on the client is configured correctly.

func (*VersionChecker) Version ¶ added in v1.7.0

func (o *VersionChecker) Version(ctx context.Context) (*Version, error)

Version determines the installed cert-manager version. First, we look for the "certificates.cert-manager.io" CRD and try to extract the version from that resource's labels. Then, if it uses a webhook, that webhook service resource's labels are checked for a label. Lastly the pods linked to the webhook its labels are checked and the image tag is used to determine the version. If no "certificates.cert-manager.io" CRD is found, the older "certificates.certmanager.k8s.io" CRD is tried too.
