    Thanks for this. MetalLB is perfect for home / lab use. All the demos on kubernetes show you how to use ingress controllers but assume you're on a cloud provider, thanks for showing us the bare metal version , works great! Great video.

    Thank you. The config has changed as of v1.25 for client and server. They now show 1 metallb.yaml and 2 configs for ipaddresspool where you define the pool then l2advertisement where you publish the pool by name. I taught myself 6502 assembly on the Apple II when I was 10 and have been going ever since. I appreciate your verifying each step so I can make sure everything is as expected. Even with lots of experience, this is a complicated system to grok. Most importantly, I learned about figlet and neofetch. ;) Hackers of the world, unite!

    Thanks for this one another great video - I was planning on giving MetalLB a try after seeing earlier video and have now run through it. I had to edit the kube-proxy config map to add the true entry for ARP. Had to do a bit of a Google to work out if that config automatically got applied, seems it doesn't and wasn't sure what method to use so deleted the individual kube-proxy pods and let K8s recreate them again presumably using the new config. It worked anyway :) I'm hoping to combine this with the NGINX ingress, using LB to expose the Ingress next - (hint for another video ;) Thanks again.

    • @justmeandopensource
      @justmeandopensource  3 года назад +2

      HI Miki, thanks for watching. Imagepullbackoff is usually because the node can't pull the image due to some networking issue or the image doesn't exist or the tag you are using for the image doesn't exist or if you are pulling from a private registry, the credentials doesn't work. Do a kubectl describe pod and see events section in the output. You might get a clue.

    This is a very good walkthrough. On the first time around, I was able to get metallb running smoothly thanks to your video with the documentation provided by MetalLB, however upon attempting to do the same thing on another cluster (4 node, bare metal, different range of IPs on these machines), I am not able to gain access once the service exposes nginx.
    I used sipcalc on the master node in my cluster and then used the last ten ip's in the range that it provided. I'm not sure if I'm doing things wrong here, do you have any advice on where to look for the usable range?

But in my vagrant environment (172.16.16.0/24 network), i use the range 172.16.16.240-172.16.16250 as the metallb range and it works consistently.

    1. hi venkat..your videos are awsome.i have a query..I created 3 vms in aws cloud and installed kubernetes cluster with calico network...I tried to create a nginx deployment and expose it as type Loadbalancer then the status is showing pending for loadbalancer ip...cloud provider not provided loadbalancer ip.
    then i installed mettalb in that cluster...the problem is that metallb takes only private ips from the pool of ips in the subnet...is there any way to get public ip for the loadbalancer for getting accessed anywhere from internet....
    2. in dns entry it is not possible to map private ip to the url any alternate to metallb which provides public ip
    3. or else how to access get external ip for loadbalancer in onpremise kubernetes cluster so that it can map to dns entry and access anywhere...

    Hi, I just did a deployment on my baremetal server using the tutorial. The difference is that I am using IPV6 addresses.IPV6 address assignment went through well. I am able to ping the external IPV6 assigned for the app from all the nodes and externally too. however, I am not able to access the IPV6:80 port using curl command from anywhere except the node on which the docker container actually running. For example, for node1 and node2 if my pod was deployed on node2, I am able to ping the app from node1 and node2 and externally too but curl -I ipv6:80 works only from node2 and nowhere else.. I dont have any firewall rules.

    • @abrakidabra

      Firstly, try with square brackets around ipv6 address if you are using curl. Secondly ensure you are using global ipv6 address. Ifconfig in your system would reveal global or local.

    Hi, its a very nice video, I created my cluster using "KinD" on My Laptop (along with Docker for Desktop on windows) and followed the instructions to create Metallb and its configmap but the external-ip for the ingress service was still showing . Can you confirm if this video is applicable for KinD environment as well ? My requirement is I need to create a multi-node cluster with the ingress service installed and want to assign a DNS to the ingress. Please let me know how to achieve it, Many thanks..

    Hi, thanks for the video! I have one question, are you able to ICMP ping the LoadBalancer IP addresses after they are assigned to the service? Like in your example 172.16.16.240/241? For me everything is working as I am able to see the default nginx page with curl/browser, but when I tried to ping, I am receiving something like:
    # ping 172.16.16.240
    PING 172.16.16.240 (172.16.16.240) 56(84) bytes of data.
    From 172.16.16.102: icmp_seq=2 Redirect Host(New nexthop: 172.16.16.240)
    Thanks!

      Hi, thanks for watching. You won't be able to ping that load balancer IP which is expected and by design. Same is the case for any service with Cluster IP.

    Hello, I'm currently learning kubernetes and planning to migrate my home media server from docker compose to k8s. I will use metallb to expose my traefik load balancer. I want to know if metallb will preserve that IP address on deployment restart. Because I will port forward my port 80 and 443 to the internet, technically I just portforward that port to the IP address from metallb right? If I restart my traefik deployment, I will get the same IP address? Because it will be very weird if I need to keep modifying my router portforward 😅

    • @justmeandopensource
      @justmeandopensource  3 года назад +2

      Hi, thanks for watching. Basically you are not changing the service and only changing the deployment by redeploying it. The service will remain the same and you will continue to use the same load balancer IP. If you delete and recreate the service you may get a different ip address.

      Sure can :) you might have to rescale the pods for it to take affect ;) ( kubectl scale -n metallb-system deploy *the name* --replicas=0 ) Or just delete the pods :P

    Dear Venkat, thank you for all your videos, github
    I notice your use the Virtualbox vboxnet0 as a private DHCP server on 172.16.16.0/24
    to provide IPs to cluster nodes, metallb and nginx deployments
    I am using Ubuntu server 20.04 to follow this video and the default config after Virtualbox installation for vboxnet0 DHCP is 192.168.56.0/24
    but the host-only interface vboxnet0 was not created and can not see on: ip a s
    I do this:
    VBoxManage hostonlyif create
    VBoxManage hostonlyif ipconfig vboxnet0 --ip 172.16.16.1
    VBoxManage dhcpserver modify --ifname vboxnet0 --ip 172.16.16.1 --netmask 255.255.255.0 --lowerip 172.16.16.2 --upperip 172.16.16.254
    VBoxManage dhcpserver modify --ifname vboxnet0 --enable
    Check changes with:
    VBoxManage list dhcpservers
    VBoxManage list hostonlyifs
