If you see a change that needs to happen to the installation instructions, please feel free to open a pull request there, we're always happy to have new contributors! diff --git a/libpod/container_internal.go b/libpod/container_internal.go index 50bd9bc25..3fcf687ec 100644 --- a/libpod/container_internal.go +++ b/libpod/container_internal.go @@ -19,7 +19,7 @@ import ( "github.com/containers/libpod/pkg/hooks" "github.com/containers/libpod/pkg/hooks/exec" "github.com/containers/libpod/pkg/rootless" - "github.com/containers/libpod/pkg/util" + "github.com/containers/libpod/pkg/selinux" "github.com/containers/storage" "github.com/containers/storage/pkg/archive" "github.com/containers/storage/pkg/mount" @@ -435,12 +435,12 @@ func (c *Container) setupStorage(ctx context.Context) error { processLabel := containerInfo.ProcessLabel switch { case c.ociRuntime.SupportsKVM(): - processLabel, err = util.SELinuxKVMLabel(processLabel) + processLabel, err = selinux.KVMLabel(processLabel) if err != nil { return err } case c.config.Systemd: - processLabel, err = util.SELinuxInitLabel(processLabel) + processLabel, err = selinux.InitLabel(processLabel) if err != nil { return err } diff --git a/libpod/container_internal_linux.go b/libpod/container_internal_linux.go index c40ad45b9..8ee0fb456 100644 --- a/libpod/container_internal_linux.go +++ b/libpod/container_internal_linux.go @@ -20,11 +20,11 @@ import ( cnitypes "github.com/containernetworking/cni/pkg/types/current" "github.com/containernetworking/plugins/pkg/ns" "github.com/containers/buildah/pkg/secrets" + "github.com/containers/common/pkg/apparmor" "github.com/containers/common/pkg/config" "github.com/containers/libpod/libpod/define" "github.com/containers/libpod/libpod/events" "github.com/containers/libpod/pkg/annotations" - "github.com/containers/libpod/pkg/apparmor" "github.com/containers/libpod/pkg/cgroups" "github.com/containers/libpod/pkg/criu" "github.com/containers/libpod/pkg/lookup" @@ -385,6 +385,16 @@ func (c *Container) generateSpec(ctx context.Context) (*spec.Spec, error) { g.AddLinuxGIDMapping(uint32(0), uint32(0), uint32(1)) } } + + for _, i := range c.config.Spec.Linux.Namespaces { + if i.Type == spec.UTSNamespace { + hostname := c.Hostname() + g.SetHostname(hostname) + g.AddProcessEnv("HOSTNAME", hostname) + break + } + } + if c.config.UTSNsCtr != "" { if err := c.addNamespaceContainer(&g, UTSNS, c.config.UTSNsCtr, spec.UTSNamespace); err != nil { return nil, err @@ -418,15 +428,6 @@ func (c *Container) generateSpec(ctx context.Context) (*spec.Spec, error) { g.AddAnnotation(annotations.ContainerManager, annotations.ContainerManagerLibpod) } - for _, i := range c.config.Spec.Linux.Namespaces { - if i.Type == spec.UTSNamespace { - hostname := c.Hostname() - g.SetHostname(hostname) - g.AddProcessEnv("HOSTNAME", hostname) - break - } - } - // Only add container environment variable if not already present foundContainerEnv := false for _, env := range g.Config.Process.Env { @@ -583,6 +584,12 @@ func (c *Container) addNamespaceContainer(g *generate.Generator, ns LinuxNS, ctr return errors.Wrapf(err, "error retrieving dependency %s of container %s from state", ctr, c.ID()) } + if specNS == spec.UTSNamespace { + hostname := nsCtr.Hostname() + g.SetHostname(hostname) + g.AddProcessEnv("HOSTNAME", hostname) + } + // TODO need unlocked version of this for use in pods nsPath, err := nsCtr.NamespacePath(ns) if err != nil { diff --git a/libpod/define/config.go b/libpod/define/config.go index 17d764c65..692eafb04 100644 --- a/libpod/define/config.go +++ b/libpod/define/config.go @@ -6,10 +6,6 @@ import ( ) var ( - // DefaultInfraImage to use for infra container - DefaultInfraImage = "k8s.gcr.io/pause:3.2" - // DefaultInfraCommand to be run in an infra container - DefaultInfraCommand = "/pause" // DefaultSHMLockPath is the default path for SHM locks DefaultSHMLockPath = "/libpod_lock" // DefaultRootlessSHMLockPath is the default path for rootless SHM locks diff --git a/libpod/define/errors.go b/libpod/define/errors.go index 3ba343789..16df2a1cc 100644 --- a/libpod/define/errors.go +++ b/libpod/define/errors.go @@ -141,4 +141,7 @@ var ( // ErrConmonOutdated indicates the version of conmon found (whether via the configuration or $PATH) // is out of date for the current podman version ErrConmonOutdated = errors.New("outdated conmon version") + + // ErrImageInUse indicates the requested operation failed because the image was in use + ErrImageInUse = errors.New("image is being used") ) diff --git a/libpod/define/pod_inspect.go b/libpod/define/pod_inspect.go index 8558c149b..26fd2cab4 100644 --- a/libpod/define/pod_inspect.go +++ b/libpod/define/pod_inspect.go @@ -18,6 +18,8 @@ type InspectPodData struct { Namespace string `json:"Namespace,omitempty"` // Created is the time when the pod was created.
