Constants ¶
const AssetDebug = false
AssetDebug is true if the assets were built with the debug flag enabled.

Functions ¶
func Asset ¶
Asset loads and returns the asset for the given name. It returns an error if the asset could not be found or could not be loaded.
func AssetDigest ¶
AssetDigest returns the digest of the file with the given name. It returns an error if the asset could not be found or the digest could not be loaded.
func AssetDir ¶
AssetDir returns the file names below a certain directory embedded in the file by go-bindata. For example if you run go-bindata on data/... and data contains the following hierarchy:
data/
foo.txt
img/
a.png
b.png
then AssetDir("data") would return []string{"foo.txt", "img"}, AssetDir("data/img") would return []string{"a.png", "b.png"}, AssetDir("foo.txt") and AssetDir("notexist") would return an error, and AssetDir("") will return []string{"data"}.
func AssetInfo ¶
AssetInfo loads and returns the asset info for the given name. It returns an error if the asset could not be found or could not be loaded.
func AssetString ¶
AssetString returns the asset contents as a string (instead of a []byte).
func MustAsset ¶
MustAsset is like Asset but panics when Asset would return an error. It simplifies safe initialization of global variables.
func MustAssetString ¶
MustAssetString is like AssetString but panics when Asset would return an error. It simplifies safe initialization of global variables.
func NewUserData ¶
NewUserData creates new user data for a given node image family
func NewUserDataForAmazonLinux2 ¶
NewUserDataForAmazonLinux2 creates new user data for Amazon Linux 2 nodes
func NewUserDataForBottlerocket ¶
NewUserDataForBottlerocket generates TOML userdata for bootstrapping a Bottlerocket node.
func NewUserDataForUbuntu ¶
NewUserDataForUbuntu creates new user data for Ubuntu 18.04 & 20.04 nodes
func NewUserDataForWindows ¶
func RestoreAsset ¶
RestoreAsset restores an asset under the given directory.
func RestoreAssets ¶
RestoreAssets restores an asset under the given directory recursively.
Types ¶
type InstanceTypeInfo ¶
type InstanceTypeInfo struct {
// Storage (ephemeral) available (GiB).
// Is 0 if not supported or none available.
Storage int64
// Max pods per node.
MaxPodsPerNode int64
// CPU count.
CPU int64
}
InstanceTypeInfo holds minimal instance info required to calculate resources to reserve.
func NewInstanceTypeInfo ¶
func NewInstanceTypeInfo(ec2info *ec2.InstanceTypeInfo) InstanceTypeInfo
NewInstanceTypeInfo creates a simple version of ec2.InstanceTypeInfo that provides functions to calculate defaults.
func (InstanceTypeInfo) DefaultCPUToReserve ¶
func (i InstanceTypeInfo) DefaultCPUToReserve() string
DefaultCPUToReserve returns the millicores to reserve.
See https://github.com/awslabs/amazon-eks-ami/blob/ff690788dfaf399e6919eebb59371ee923617df4/files/bootstrap.sh#L183-L208 which takes it form https://cloud.google.com/kubernetes-engine/docs/concepts/cluster-architecture#node_allocatable
6% of the first core 1% of the next core (up to 2 cores) 0.5% of the next 2 cores (up to 4 cores) 0.25% of any cores above 4 cores
func (InstanceTypeInfo) DefaultMemoryToReserve ¶
func (i InstanceTypeInfo) DefaultMemoryToReserve() string
DefaultMemoryToReserve returns how much memory to reserve.
func (InstanceTypeInfo) DefaultStorageToReserve ¶
func (i InstanceTypeInfo) DefaultStorageToReserve() string
DefaultStorageToReserve returns how much storage to reserve.
See https://github.com/awslabs/amazon-eks-ami/blob/ff690788dfaf399e6919eebb59371ee923617df4/files/bootstrap.sh#L306 This is always 1GiB
