k3d-bsed Setup

⚡️ Quicker Paralllel Steps

The below will be quicker than above if you use multiple terminals to run them in parallel.

Details

Prep - run before all

{
    pushd certs > /dev/null

    make -f ../tools/certs/Makefile.selfsigned.mk root-ca

    make -f ../tools/certs/Makefile.selfsigned.mk armadillo-cacerts
    make -f ../tools/certs/Makefile.selfsigned.mk bison-cacerts
    make -f ../tools/certs/Makefile.selfsigned.mk dolphin-cacerts

    popd > /dev/null
}

Bison

{
    k3d cluster create bison --agents 1 -p "32022:32022@agent[0]"

    kubectl create namespace --context k3d-bison istio-system
    kubectl create secret --context k3d-bison \
        generic cacerts -n istio-system \
        --from-file=./certs/bison/ca-cert.pem \
        --from-file=./certs/bison/ca-key.pem \
        --from-file=./certs/bison/root-cert.pem \
        --from-file=./certs/bison/cert-chain.pem

    istioctl install --context k3d-bison -f clusters/bison/istioctl-input.yaml

    kubectl label --context k3d-bison namespace default istio-injection=enabled
    kubectl apply --context k3d-bison \
        -f tools/httpbin/httpbin.yaml \
        -f tools/toolkit-alpine/toolkit-alpine.yaml

    kubectl apply --context k3d-bison \
        -f clusters/bison/bison-services.yaml \
        -f clusters/bison/multicluster-setup.yaml
}

If you are using Istio v1.6 or below, you would need to run the following command as EnvoyFilter change in 1.7 is not compatible.

{
    kubectl apply --context k3d-bison \
        -f clusters/bison/multicluster-setup-1.6.yaml
}

Dolphin

{
    k3d cluster create dolphin --agents 1 -p "32024:32024@agent[0]"

    kubectl create namespace --context k3d-dolphin istio-system
    kubectl create secret --context k3d-dolphin \
        generic cacerts -n istio-system \
        --from-file=./certs/dolphin/ca-cert.pem \
        --from-file=./certs/dolphin/ca-key.pem \
        --from-file=./certs/dolphin/root-cert.pem \
        --from-file=./certs/dolphin/cert-chain.pem

    istioctl install --context k3d-dolphin -f clusters/dolphin/istioctl-input.yaml

    kubectl label --context k3d-dolphin namespace default istio-injection=enabled
    kubectl apply --context k3d-dolphin \
        -f tools/httpbin/httpbin.yaml \
        -f tools/toolkit-alpine/toolkit-alpine.yaml

    kubectl apply --context k3d-dolphin \
        -f clusters/dolphin/dolphin-services.yaml \
        -f clusters/dolphin/multicluster-setup.yaml
}

If you are using Istio v1.6 or below, you would need to run the following command as EnvoyFilter change in 1.7 is not compatible.

{
    kubectl apply --context k3d-dolphin \
        -f clusters/dolphin/multicluster-setup-1.6.yaml
}

Armadillo

NOTE: Armadillo has a dependency to Bison and Dolphin, so set up those clusters first.

{
    k3d cluster create armadillo --agents 1 -p "32021:32021@agent[0]"

    kubectl create namespace --context k3d-armadillo istio-system
    kubectl create secret --context k3d-armadillo \
        generic cacerts -n istio-system \
        --from-file=./certs/armadillo/ca-cert.pem \
        --from-file=./certs/armadillo/ca-key.pem \
        --from-file=./certs/armadillo/root-cert.pem \
        --from-file=./certs/armadillo/cert-chain.pem

    istioctl install --context k3d-armadillo -f clusters/armadillo/istioctl-input.yaml

🧹 Cleanup

{
    rm -rf certs
    git reset --hard
    k3d cluster delete armadillo
    k3d cluster delete bison
    k3d cluster delete dolphin
}
