Docker build inside kubernetes pod fails with "could not find bridge docker0" -

-

i moved our build agents kubernetes / container engine. used run on container vm (version container-vm-v20160321) , mount docker.sock docker container can run docker build inside container.

this used following manifest:

apiversion: v1 kind: pod metadata:   name: gocd-agent spec:   containers:   - name: gocd-agent     image: travix/gocd-agent:16.8.0     imagepullpolicy:     volumemounts:     - name: ssh-keys       mountpath: /var/go/.ssh       readonly: true     - name: gcloud-keys       mountpath: /var/go/.gcloud       readonly: true     - name: docker-sock       mountpath: /var/run/docker.sock     - name: docker-bin       mountpath: /usr/bin/docker     env:     - name: "go_server_url"       value: "https://server:8154/go"     - name: "agent_key"       value: "***"     - name: "agent_resources"       value: "docker"     - name: "docker_gid_on_host"       value: "107"   restartpolicy:   dnspolicy: default   volumes:   - name: ssh-keys     gcepersistentdisk:       pdname: sh-keys       fstype: ext4       readonly: true   - name: gcloud-keys     gcepersistentdisk:       pdname: gcloud-keys       fstype: ext4       readonly: true   - name: docker-sock     hostpath:       path: /var/run/docker.sock   - name: docker-bin     hostpath:       path: /usr/bin/docker   - name: varlog     hostpath:       path: /var/log   - name: varlibdockercontainers     hostpath:       path: /var/lib/docker/containers

now after moving full-blown container engine cluster - version 1.3.5 - following manifest fails.

apiversion: extensions/v1beta1 kind: deployment metadata:   name: gocd-agent spec:   replicas: 2   strategy:     type: recreate   revisionhistorylimit: 1   selector:     matchlabels:       app: gocd-agent   template:     metadata:       labels:         app: gocd-agent     spec:       containers:       - name: gocd-agent         image: travix/gocd-agent:16.8.0         imagepullpolicy:         securitycontext:           privileged: true         volumemounts:         - name: ssh-keys           mountpath: /k8s-ssh-secret         - name: gcloud-keys           mountpath: /var/go/.gcloud         - name: docker-sock           mountpath: /var/run/docker.sock         - name: docker-bin           mountpath: /usr/bin/docker         env:         - name: "go_server_url"           value: "https://server:8154/go"         - name: "agent_key"           value: "***"         - name: "agent_resources"           value: "docker"         - name: "docker_gid_on_host"           value: "107"       volumes:       - name: ssh-keys         secret:           secretname: ssh-keys       - name: gcloud-keys         secret:           secretname: gcloud-keys       - name: docker-sock         hostpath:           path: /var/run/docker.sock       - name: docker-bin         hostpath:           path: /usr/bin/docker       - name: varlog         hostpath:           path: /var/log       - name: varlibdockercontainers         hostpath:           path: /var/lib/docker/containers

it seems start building fine, fails no such interface error:

is impossible run docker build inside pod due kubernetes networking or need configure pod differently? or bug in particular docker version on host?

client:  version:      1.11.2  api version:  1.23  go version:   go1.5.4  git commit:   b9f10c9  built:        wed jun  1 21:20:08 2016  os/arch:      linux/amd64 server:  version:      1.11.2  api version:  1.23  go version:   go1.5.4  git commit:   b9f10c9  built:        wed jun  1 21:20:08 2016  os/arch:      linux/amd64

the bridge seems exist on host:

$ sudo brctl show  bridge name     bridge id               stp enabled     interfaces cbr0            8000.063c847a631e       no              veth0a58740b                                                         veth1f558898                                                         veth8797ea93                                                         vethb11a7490                                                         vethc576cc01 docker0         8000.02428db6a46e       no

and docker info completeness
