DefaultSysSpec is the default SysSpec.
Functions ¶
Types ¶
type CgroupsValidator ¶
type CgroupsValidator struct{}
func (*CgroupsValidator) Name ¶
func (c *CgroupsValidator) Name() string
func (*CgroupsValidator) Validate ¶
func (c *CgroupsValidator) Validate(spec SysSpec) error
type DockerSpec ¶
type DockerSpec struct { // Version is a group of regex matching supported docker versions. Version []string // GraphDriver is the graph drivers supported by kubelet. GraphDriver []string }
DockerSpec defines the requirement configuration for docker. Currently, it only contains spec for graph driver.
type DockerValidator ¶
type DockerValidator struct{}
DockerValidator validates docker configuration.
func (*DockerValidator) Name ¶
func (d *DockerValidator) Name() string
func (*DockerValidator) Validate ¶
func (d *DockerValidator) Validate(spec SysSpec) error
TODO(random-liu): Add more validating items.
type KernelConfig ¶
type KernelConfig struct { // Name is the general name of the kernel configuration. It is used to // match kernel configuration. Name string // Aliases are aliases of the kernel configuration. Some configuration // has different names in different kernel version. Names of different // versions will be treated as aliases. Aliases []string // Description is the description of the kernel configuration, for example: // * What is it used for? // * Why is it needed? // * Who needs it? Description string }
KernelConfig defines one kernel configration item.
type KernelSpec ¶
type KernelSpec struct { // Versions define supported kernel version. It is a group of regexps. Versions []string // Required contains all kernel configurations required to be enabled // (built in or as module). Required []KernelConfig // Optional contains all kernel configurations are required for optional // features. Optional []KernelConfig // Forbidden contains all kernel configurations which areforbidden (disabled // or not set) Forbidden []KernelConfig }
KernelSpec defines the specification for the kernel. Currently, it contains specification for:
- Kernel Version
- Kernel Configuration
type KernelValidator ¶
type KernelValidator struct {
// contains filtered or unexported fields
}
KernelValidator validates kernel. Currently only validate kernel version and kernel configuration.
func (*KernelValidator) Name ¶
func (k *KernelValidator) Name() string
func (*KernelValidator) Validate ¶
func (k *KernelValidator) Validate(spec SysSpec) error
type OSValidator ¶
type OSValidator struct{}
func (*OSValidator) Name ¶
func (c *OSValidator) Name() string
func (*OSValidator) Validate ¶
func (c *OSValidator) Validate(spec SysSpec) error
type RuntimeSpec ¶
type RuntimeSpec struct {
*DockerSpec
}
RuntimeSpec is the abstract layer for different runtimes. Different runtimes should put their spec inside the RuntimeSpec.
type SysSpec ¶
type SysSpec struct { // OS is the operating system of the SysSpec. OS string // KernelConfig defines the spec for kernel. KernelSpec KernelSpec // Cgroups is the required cgroups. Cgroups []string // RuntimeSpec defines the spec for runtime. RuntimeSpec RuntimeSpec }
SysSpec defines the requirement of supported system. Currently, it only contains spec for OS, Kernel and Cgroups.
