Add readiness check for docker container (#9804) * Update Dockerfile Since parity is built for "mission critical use", I thought other operators may see the need for this. Adding the `curl` and `jq` commands allows for an extremely simple health check to be usable in container orchestrators. For example. Here is a health check for a parity docker container running in Kubernetes. This can be setup as a readiness Probe that would prevent clustered nodes that aren't ready from serving traffic. ```bash #!/bin/bash ETH_SYNCING=$(curl -X POST --data '{"jsonrpc":"2.0","method":"eth_syncing","params":[],"id":1}' http://localhost:8545 -H 'Content-Type: application/json') RESULT=$(echo "$ETH_SYNCING \| jq -r .result) if [ "$RESULT" == "false" ]; then echo "Parity is ready to start accepting traffic" exit 0 else echo "Parity is still syncing the blockchain" exit 1 fi ``` * add sync check script 2018-10-26 13:51:08 +02:00			`#!/bin/bash`
