Functions ¶

func GenerateSpec ¶

func GenerateSpec(ctx context.Context, meta executor.Meta, mounts []executor.Mount, id, resolvConf, hostsFile string, namespace network.Namespace, processMode ProcessMode, idmap *idtools.IdentityMapping, opts ...oci.SpecOpts) (*specs.Spec, func(), error)

GenerateSpec generates spec using containerd functionality. opts are ignored for s.Process, s.Hostname, and s.Mounts .

func GetHostsFile ¶

func GetHostsFile(ctx context.Context, stateDir string, extraHosts []executor.HostIP, idmap *idtools.IdentityMapping) (string, func(), error)

func GetMounts ¶

func GetMounts(ctx context.Context, mountOpts ...MountOpts) ([]specs.Mount, error)

GetMounts returns default required for buildkit https://github.com/moby/buildkit/issues/429

func GetResolvConf ¶

func GetResolvConf(ctx context.Context, stateDir string, idmap *idtools.IdentityMapping, dns *DNSConfig) (string, error)

func GetUser ¶

func GetUser(ctx context.Context, root, username string) (uint32, uint32, []uint32, error)

func ParseUIDGID ¶

func ParseUIDGID(str string) (uid uint32, gid uint32, err error)

ParseUIDGID takes the fast path to parse UID and GID if and only if they are both provided

func WithUIDGID ¶

func WithUIDGID(uid, gid uint32, sgids []uint32) containerdoci.SpecOpts

WithUIDGID allows the UID and GID for the Process to be set FIXME: This is a temporeray fix for the missing supplementary GIDs from containerd once the PR in containerd is merged we should remove this function.

Types ¶

type DNSConfig ¶

type DNSConfig struct {
	Nameservers   []string
	Options       []string
	SearchDomains []string
}

type MountOpts ¶

type MountOpts func([]specs.Mount) ([]specs.Mount, error)

MountOpts sets oci spec specific info for mount points

type ProcessMode ¶

type ProcessMode int

ProcMode configures PID namespaces

const (
	// ProcessSandbox unshares pidns and mount procfs.
	ProcessSandbox ProcessMode = iota
	// NoProcessSandbox uses host pidns and bind-mount procfs.
	// Note that NoProcessSandbox allows build containers to kill (and potentially ptrace) an arbitrary process in the BuildKit host namespace.
	// NoProcessSandbox should be enabled only when the BuildKit is running in a container as an unprivileged user.
	NoProcessSandbox
)
