+Set up the environment for running peer commands and check everything is working.
+
+```

+
+Deploy the chaincode package as usual, starting by installing the k8s chaincode package.
+
+```shell
+peer lifecycle chaincode install go-contract-v0.7.2.tgz
+```
+
+Export a `PACKAGE_ID` environment variable for use in the following commands.
+
+```shell
+export PACKAGE_ID=$(peer lifecycle chaincode calculatepackageid go-contract-v0.7.2.tgz) && echo $PACKAGE_ID
+```
+
+Note: the `PACKAGE_ID` must match the chaincode code package identifier shown by the `peer lifecycle chaincode install` command.
+
+Approve the chaincode.
+
+```shell
+peer lifecycle chaincode approveformyorg -o 127.0.0.1:6050 --channelID mychannel --name sample-contract --version 1 --package-id $PACKAGE_ID --sequence 1 --tls --cafile ${PWD}/crypto-config/ordererOrganizations/example.com/orderers/orderer.example.com/tls/ca.crt
+```

+Commit the chaincode.
