Had setup K8s cluster using Kops
export KOPS_STATE_STORE=s3://clusters.aind.devops
export ZONES=ap-south-1a
export VPC=vpc-xxxxx
export node_count=2
export node_size=m4.large
export master_size=t2.medium
export api_loadbalancer_type=public
export topology=private
export dns=private
export dns_zone=Z25L42E21ILH89
export CLIENT=test
It created 2 node and one master And i tried to setup Jenkins docker build slave to build the docker images in the pod
My build is failing with
Sending build context to Docker daemon 15.36 kB
Step 1/3 : FROM ubuntu
---> cd6d8154f1e1
Step 2/3 : RUN apt-get update -y
---> Using cache
---> 8007c6693623
Step 3/3 : RUN apt-get install vim -y
---> Running in cbbafcb6a37b
Reading package lists...
Building dependency tree...
Reading state information...
E: Unable to locate package vim
The command '/bin/sh -c apt-get install vim -y' returned a non-zero code: 100
When I logged into the node and ran the same build its failing there, seems docker daemon is not getting the DNS resoultion
Please help
Why are you building images in the cluster? The proper way to do it would be to:
creating a local docker registry:
As for why it can't locate the vim package check network connectivity by pinging 8.8.8.8 . By default, if the node has internet connectivity, the docker daemon has too.
