building a master localy.
I am trying to use /kubernetes/docs/getting-started-guides/docker-multinode/master.sh
master is done!
some detail imformation:
K8S_VERSION is set to: 1.2.4
ETCD_VERSION is set to: 2.2.1
FLANNEL_VERSION is set to: 0.5.5
FLANNEL_IFACE is set to: wlan0
FLANNEL_IPMASQ is set to: true

vDOCKER_OPTS="$DOCKER_OPTS --mtu=1450 --bip=10.1.48.1/24"
next add a vagrant virtualbox slave to master.
trying to use /kubernetes/docs/getting-started-guides/docker-multinode/worker.sh it bring some issue:

I have two vm,
one is on public_network:192.168.1.110
other is on private_network:192.168.50.2
all is the same error output.
ps: can I use the worker.sh in aws ec2?
question is a bit miscellaneous,
hoping a cattle help me to consolidation.
I am lucky enough to pass the work node, but I don't know the exactly reason.
now I package the vagrant box in my google cloud disk, url is below----[https://drive.google.com/file/d/0B9WzutmgDDrodkpLRGM2c0J1RXc/view?usp=sharing][1].
before you take a public or private network with it, you should download a pre-compiled kubernetes version, and copy it to the vagrant folder.
use vagrant init kube-slave to start.

I got a bit stuck debugging a yocto build problem. I encountered this while updating from yocto warrior (2.7) to yocto dunfell (3.1) The build fails during the building of the rootfs, all steps before seem to work:

It seems that systemd-1:244.5 depends on update-rc.d. This doesn't make a lot sense to me, since I don't need those scripts anymore when using systemd - maybe there are for some compatibility reasons? Puzzled by this I checked the reference and it seems that I have the right settings to use systemd exclusively:
$ bitbake -e exos-develop | grep "^DISTRO_FEATURES"
DISTRO_FEATURES="acl alsa argp bluetooth ext2 ipv4 ipv6 largefile pcmcia usbgadget usbhost wifi xattr nfs zeroconf pci 3g nfc x11 vfat largefile opengl ptest multiarch wayland vulkan systemd weston wayland sota usrmerge systemd systemd pulseaudio gobject-introspection-data ldconfig"
DISTRO_FEATURES_BACKFILL="pulseaudio sysvinit gobject-introspection-data ldconfig"

DISTRO_FEATURES_FILTER_NATIVE="api-documentation"
DISTRO_FEATURES_FILTER_NATIVESDK="api-documentation"
DISTRO_FEATURES_NATIVE="x11 ipv6 xattr sota"
DISTRO_FEATURES_NATIVESDK="x11"
During debugging I also saw that poky's systemd recipe uses the update-rc.d.bbclass. From what I can see it only gets active when the DISTRO_FEATURES contain sysvinit, which is apparently not the case here. Maybe some caching issue?
Any ideas how I can debug this further?
I found it out myself (interesting how asking questions helps you thinking...):
The issue was in the systemd recipe itself and related to the systemd-compat-units recipe. I was able to fix it with this in my layer's recipes-core/systemd/systemd_%.bbappend:
# Disable all relations to update-rc.d:
PACKAGECONFIG_remove = "sysvinit"
RRECOMMENDS_${PN}_remove = "systemd-compat-units"
I'm still wondering how this issue came to be at all, though.
Would be great if somebody could explain why this happened at all.
I'm trying to use CRC for testing Openshift 4 on my laptop (Ubuntu 20). CRC version 1.17 doesn't support Virtualbox virtualizazion so following the setup instructions
https://access.redhat.com/documentation/en-us/red_hat_codeready_containers/1.17/html/getting_started_guide/installation_gsg
i'm using libvirt, but when i start the cluster with crc start it launch following error

I have not experiences with libvirt so i'm stuck on that and online i'm not finding anything...
Thanks
There is an issue with the crc_libvirt_4.5.14 image. The easiest way to fix it is to do a
qemu-img rebase -f qcow2 -F qcow2 -b /home/${USER}/.crc/cache/crc_libvirt_4.5.14/crc.qcow2 /home/${USER}/.crc/machines/crc/crc.qcow2
Now, if you try to do a crc start, you going to face a "Permission denied" error, which is related to Apparmor, unless you whitelisted your home directory. If you don't want to hack around with Apparmor settings, the /var/lib/libvirt/images supposed to be whitelisted. Move the image to there:
sudo mv /home/${USER}/.crc/machines/crc/crc.qcow2 /var/lib/libvirt/images
then edit the virtual machine settings pointing to the new image location: virsh edit crc , then replace the <source file='/home/yourusername/.crc/machines/crc/crc.qcow2'/> to <source file='/var/lib/libvirt/images/crc.qcow2'/>.
Then do the crc start and... that's it.

I follow the instructions to bootstrap a new Ceph (I'm new to Ceph) cluster.
I got the following error:

What does it mean ? How to fix it ?
cephadm is still fairly new. I've tracked a few days ago in:
https://tracker.ceph.com/issues/44828
Please run
ceph config set mon public_network <mon_network>
after bootstrap finished.
Is this the exact command you ran?
sudo cephadm bootstrap --mon-ip *<mon-ip>*
If so you actually need to replace *<mon-ip>* with the actual IP address that you want the monitor daemon to listen on.
For future reference, on that page, any command you see that has a variable surrounded by asterisks is something you would need to replace with an address/host/hostname etc. that applies to your environment.
I have a k8s_object rule to apply a deployment to my Google Kubernetes Cluster. Here is my setup:
load("#io_bazel_rules_docker//nodejs:image.bzl", "nodejs_image")
nodejs_image(
name = "image",
data = [":lib", "//:package.json"],
entry_point = ":index.ts",
)
load("#io_bazel_rules_k8s//k8s:object.bzl", "k8s_object")
k8s_object(
name = "k8s_deployment",
template = ":gateway.deployment.yaml",
kind = "deployment",
cluster = "gke_cents-ideas_europe-west3-b_cents-ideas",
images = {
"gcr.io/cents-ideas/gateway:latest": ":image"
},
)
But when I run bazel run //services/gateway:k8s_deployment.apply, I get the following error

It doesn't push the new image to the Google Container Registry.
Strangely, this worked a few days ago. But I didn't change anything.

Update
I don't know if this has something to do with this issue but when I run
gcloud auth configure-docker
I get some warnings:

I had google-cloud-sdk installed via snap install. What I did to make it work is to remove google-cloud-sdk via
snap remove google-cloud-sdk
and then followed those instructions to install it via
sudo apt install google-cloud-sdk
Now it works fine
I have Docker installed under CentOS Linux 7.6.1810 and Plesk Onyx 17.8.11, and everything was fine. For a few hours I can't start mongoDB or Docker anymore.
I get this error message
{"message":"OCI runtime create failed: container_linux.go:344: starting container process caused \"process_linux.go:297: getting the final child's pid from pipe caused \\\"read init-p: connection reset by peer\\\"\": unknown"}
What could it be?
I have fixed it, I downgraded containerd.io to the version 1.2.0 and Docker is running.
Docker-ce 18.09.2 + Linux Kernel 3.10.0 produces the same problem as you. If we want to use Docker-ce 18.09.2, Linux Kernel 4.x+ is required.
