Fabric v2.0 in kubernetes (minikube) - error Peer channel join - TLS issue because of pod's names

We had a similar dot/dash certificate issue with OpenShift and solved it by setting a CommonName with dashes for each Host in our crypto-config file. Maybe this will work for you too.

Something like this:

PeerOrgs:  - Name: Org1    Domain: org1-example-com    EnableNodeOUs: true    Specs:      - Hostname: peer0        CommonName: "peer0-org1-example-com"      - Hostname: peer1        CommonName: "peer1-org1-example-com"    CA:      Hostname: ca      CommonName: "ca-org1-example-com"

PeerOrgs:  - Name: Org2    Domain: org2-example-com    EnableNodeOUs: true    Specs:      - Hostname: peer0        CommonName: "peer0-org2-example-com"      - Hostname: peer1        CommonName: "peer1-org2-example-com"    CA:      Hostname: ca      CommonName: "ca-org2-example-com"

OrdererOrgs:  - Name: Orderer    Domain: example.com    EnableNodeOUs: true    Specs:      - Hostname: orderer        CommonName: "orderer-example-com"

UPDATE:We also changed all dot addresses in the configtx.yaml like this:

Orderer: &OrdererDefaults    ...    EtcdRaft:        Consenters:        - Host: orderer-example-com    ...    Addresses:        - orderer-example-com:7050

UPDATE 2:probably you have to change the csr part in the fabric-ca-server-config.yaml of each org too:

csr:   cn: ca-example-com   names:      - C: US        ST: "New York"        L: "New York"        O: example-com        OU:   hosts:     - localhost     - example-com   ca:      expiry: 131400h      pathlength: 1

csr:   cn: ca-org1-example-com   names:      - C: US        ST: "North Carolina"        L: "Durham"        O: org1-example-com        OU:   hosts:     - localhost     - org1-example-com   ca:      expiry: 131400h      pathlength: 1

csr:   cn: ca-org2-example-com   names:      - C: UK        ST: "Hampshire"        L: "Hursley"        O: org2-example-com        OU:   hosts:     - localhost     - org2-example-com   ca:      expiry: 131400h      pathlength: 1
