env

There are 2 ENV values, one is for the harbor registry FQDN, another is used for the  workspace of image to store

harborurl=your-harbor.com
project=catalog-apps

Install the certificate on the machine

we leverage the openssl  to get certificate from harbor registry and store it in docker configure path. 

sudo mkdir -p /etc/docker/certs.d/${harborurl}
 
openssl s_client -showcerts  -connect registry.${harborurl}:443 </dev/null | awk '/-----BEGIN CERTIFICATE-----/,/-----END CERTIFICATE-----/' |sudo tee -a /etc/docker/certs.d/${harborurl}/ca.crt

or alternative way: 

wget --no-proxy http://${harborurl}:8081/ca.crt
sudo mkdir -p /etc/docker/certs.d/${harborurl}
sudo mv ca.crt /etc/docker/certs.d/${harborurl}
sudo systemctl restart docker

On edge node

Add the certificate to the trust pool

sudo cp ca.crt /usr/local/share/ca-certificates/habor-ca.crt
 
sudo update-ca-certificates --fresh

Login the harbor registry

run this command on orchestrator server to get the the credential of harbor registry.

 

credential=$(kubectl get -n harbor secrets harbor-admin-credential -o json | jq .metadata.annotations | grep -oP "(?<=\"credential).*(?=}})" | tr -d '"\')
credential=${credential#:}
echo "credential=$credential"

Note

NOTE: copy the above print to edge node.

#  Username: admin; Password: Harbor12345
user=${credential%:*}
pass=${credential#*:}
docker login ${harborurl}

Docker push

push your docker image to harbor registry

dockimg=test
ov=latest
nv=latest
 
docker tag $dockimg:$ov ${harborurl}/${project}/$dockimg:$nv
docker push ${harborurl}/${project}/$dockimg:$nv

Push helm chart

first install helm tool.

curl https://baltocdn.com/helm/signing.asc | gpg --dearmor | sudo tee /usr/share/keyrings/helm.gpg > /dev/null
sudo apt-get install apt-transport-https --yes
echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/helm.gpg] https://baltocdn.com/helm/stable/debian/ all main" | sudo tee /etc/apt/sources.list.d/helm-stable-debian.list
sudo apt-get update
sudo apt-get install helm

check your helm-chart before you push to harbor registry

chart=mychartpath
helm install . --dry-run --debug ./$chart

then push your helm chart to harbor registry

 

chartball=xxx.tgz
chratpath=<helm-dir>
reponame=iotedge-repo
tar czvf $chartball $chratpath
 
 
helm plugin install https://github.com/chartmuseum/helm-push
helm repo add --username ${user} --password ${pass} --ca-file /etc/docker/certs.d/${harborurl}/ca.crt $reponame https://registry.${harborurl}/chartrepo/${project}
helm cm-push -u ${user} -p ${pass} --ca-file /etc/docker/certs.d/${harborurl}/ca.crt $chartball $reponame

Batch Push helm charts

for SUBDIR in */; do
 
    # Remove trailing slash
    SUBDIR_NAME="${SUBDIR%/}"
    echo $SUBDIR_NAME
 
    if [ -e $SUBDIR_NAME/Chart.yaml ]
    then
        echo "This is a Helm Chart file"
        tar -czf "${SUBDIR_NAME}.tgz" "$SUBDIR_NAME"
        helm cm-push -u ${user} -p ${pass} --ca-file /etc/docker/certs.d/${harborurl}/ca.crt ${SUBDIR_NAME}.tgz $reponame
        rm ${SUBDIR_NAME}.tgz
    else
        echo "Not a Helm Chart file, skip"
    fi
done

Trouble shooting

upload the certs into new cluster

mkdir -p /opt/certs
cd /opt/certs
wget --no-proxy http://${harborurl}:8081/ca.crt
wget --no-proxy http://${harborurl}:8081/harbor.com.crt
wget --no-proxy http://${harborurl}:8081/harbor.com.key

update the rke2 registry

$ cat /etc/rancher/rke2/registries.yaml
---
# Define the proxy registry to pull images from
mirrors:
  zz-iotedge-harbor.sh.intel.com:
    endpoint:
      - "https://zz-iotedge-harbor.sh.intel.com"
 
configs:
  "zz-iotedge-harbor.sh.intel.com":
    auth:
      username: admin
      password: 1q2w3e@intelQ_0
    tls:
      cert_file: /opt/certs/harbor.com.crt
      key_file: /opt/certs/harbor.com.key
      ca_file: /opt/certs/ca.crt
      insecure_skip_verify: true

restart the service

$ sudo systemctl restart rke2-server
# Make sure it's in effect.
$ sudo cat /var/lib/rancher/rke2/agent/etc/containerd/config.toml
[plugins."io.containerd.grpc.v1.cri".registry.configs."zz-iotedge-harbor.sh.intel.com".auth]
