Adding Orderer To An Existing Network

[fernandohackbart]

What happened?

I am trying to add a new orderer of on existing ordering organization to a channel by following the documentation available at https://hyperledger-fabric.readthedocs.io/en/latest/create_channel/add_orderer.html, we already have a channel deployed using HLF operator. I the procedure is required to get the last config block and is suggested to use the peer channel fetch config command.

I would like to know how to do this with the operator.

What did you expect to happen?

To have a kubectl hlf command to get the last configuration block for the channel.

How can we reproduce it (as minimally and precisely as possible)?

This is not an operation issue but a how to question.

Anything else we need to know?

No response

Kubernetes version

```console # kubectl get nodes -o wide ```

The procedure I am using is

kubectl exec -it -n regulators -c peer r-timestamp-1peer01-6f9cb874ff-pxcq8 -- peer channel fetch config /tmp/usage_latest.pb -o r-timestamp-1orderer.regulators:7050 --ordererTLSHostnameOverride r-timestamp-1orderer.regulators -c usage --tls --cafile /var/hyperledger/tls/client/cert/cert.pem
kubectl cp -nregulators -c peer  r-timestamp-1peer01-6f9cb874ff-pxcq8:/tmp/usage_latest.pb /tmp/usage_latest.pb
configtxlator proto_decode --input /tmp/usage_latest.pb --type common.Block --output /tmp/usage-add-orderer-01-full.json
jq .data.data[0].payload.data.config /tmp/usage-add-orderer-01-full.json > /tmp/usage-add-orderer-01.json
kubectl hlf ordnode join --block=/hyperledger/channels/usage.block --name=r-timestamp-1orderer-01 --identity=/hyperledger/config/r-timestamp-1/admin-tlsca-certs.yaml --namespace=regulators
cat /tmp/usage-add-orderer-01.json | jq '.channel_group.groups.Orderer.groups."r-timestamp-1msp".values.Endpoints'
cat /tmp/usage-add-orderer-01.json | jq '.channel_group.groups.Orderer.policies.BlockValidation.policy.value.identities' 
cat /tmp/usage-add-orderer-01.json | jq '.channel_group.groups.Orderer.policies.BlockValidation.policy.value.rule' 
cat /tmp/usage-add-orderer-01.json | jq '.channel_group.groups.Orderer.values.Orderers.value.consenter_mapping' 
vi /tmp/usage-add-orderer-01.json
### adjust the file
configtxlator proto_encode --input=/tmp/usage-add-orderer-01.json --type=common.ConfigUpdate --output=/tmp/usage-add-orderer-01.pb

When executing the configtxlator proto_encode command it fails with configtxlator: error: Error decoding: error decoding input: *commonext.ConfigUpdate: unknown field "channel_group" in common.ConfigUpdate error.
