Kubernetes Production

Install kops

curl -LO https://github.com/kubernetes/kops/releases/download/$(curl -s https://api.github.com/repos/kubernetes/kops/releases/latest | grep tag_name | cut -d '"' -f 4)/kops-linux-amd64 chmod +x kops-linux-amd64 sudo mv kops-linux-amd64 /usr/local/bin/kops

Install AWS CLI

https://docs.aws.amazon.com/cli/latest/userguide/install-bundle.html

curl "https://s3.amazonaws.com/aws-cli/awscli-bundle.zip" -o "awscli-bundle.zip" unzip awscli-bundle.zip sudo ./awscli-bundle/install -i /usr/local/aws -b /usr/local/bin/aws

aws configure

account ID = account Secret = region = us-west-1 output = json

To test our AWS CLI use this command

aws ec2 describe-availability-zones --region us-west-1

export KOPS_STATE_STORE=s3://

Commands to create network

ssh-keygen (No passphrase)

kops create cluster hyperledger.k8s.local --zones us-west-1b,us-west-1c --node-count 3 --master-zones us-west-1b,us-west-1c --master-count 3 --authorization AlwaysAllow --yes

kops delete cluster hyperledger.k8s.local

Commands to copy over files to kubernetes storage

kubectl cp ./s5-connecting-everything/scripts $(kubectl get pods -o=name | grep ca-client-deployment | sed "s/^.{4}//"):/ kubectl cp ./config.yaml $(kubectl get pods -o=name | grep ca-client-deployment | sed "s/^.{4}//"):/files kubectl cp ./s5-connecting-everything/chaincode/rawresources $(kubectl get pods -o=name | grep ca-client-deployment | sed "s/^.{4}//"):/scripts/chaincode kubectl cp ./configtx.yaml $(kubectl get pods -o=name | grep ca-client-deployment | sed "s/^.{4}//"):/scripts kubectl cp ./bin $(kubectl get pods -o=name | grep ca-client-deployment | sed "s/^.{4}//"):/scripts

Adding nginx to our network

kubectl apply -f https://raw.githubusercontent.com/kubernetes/kops/master/addons/ingress-nginx/v1.6.0.yaml

Adding secrets

kubectl create secret generic couchdb --from-literal username=nick --from-literal password=1234
