To update the anchor peer for the Org2 organization while creating a channel in Hyperledger Fabric, you would use the following Docker command:

```bash
docker exec -e "CORE_PEER_LOCALMSPID=Org2MSP" -e "CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/msp/users/Admin@org2.example.com/msp" peer0.org2.example.com peer channel update -o orderer.example.com:7050 -c $CHANNEL_NAME -f ./channel-artifacts/Org2MSPanchors.tx
```

Here's a step-by-step breakdown of the command:

1. `docker exec`: This command is used to run a new command in a running container.

2. `-e "CORE_PEER_LOCALMSPID=Org2MSP"`: This sets the environment variable `CORE_PEER_LOCALMSPID` to `Org2MSP`. This is used to specify the MSP ID of the peer's organization.

3. `-e "CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/msp/users/Admin@org2.example.com/msp"`: This sets the environment variable `CORE_PEER_MSPCONFIGPATH` to the path of the MSP configuration for the admin user of Org2.

4. `peer0.org2.example.com`: This is the name of the Docker container for the peer.

5. `peer channel update`: This is the command to update the channel.

6. `-o orderer.example.com:7050`: This specifies the orderer endpoint.

7. `-c $CHANNEL_NAME`: This specifies the name of the channel.

8. `-f ./channel-artifacts/Org2MSPanchors.tx`: This specifies the file that contains the configuration update for setting the anchor peer for Org2.
