GRPCUnavailableError:UNAVAILABLE: No connection established

[AhmedZahRan7]

It's just happened when trying running the quick-start in the redmi file

const { Etcd3 } = require('etcd3');
const client = new Etcd3();

(async () => {
    await client.put('foo').value('bar');

    const fooValue = await client.get('foo').string();
    console.log('foo was:', fooValue);

    const allFValues = await client.getAll().prefix('f').keys();
    console.log('all our keys starting with "f":', allFValues);

    await client.delete().all();
})();

The output error is:

node:internal/process/promises:279
            triggerUncaughtException(err, true /* fromPromise */);
            ^
GRPCUnavailableError: 14 UNAVAILABLE: No connection established

Node version is 17.6.0

Check if your etcd is using a certfile

Example in docker-compose.yml

      - /usr/local/bin/etcd
      - --data-dir=/data
      - --name=etcdv3
      - --advertise-client-urls=https://etcdv3:2379
      - --listen-client-urls=https://0.0.0.0:2379
      - --cert-file=/etc/etcd/etcdv3.mycert.com.br.crt
      - --key-file=/etc/etcd/etcdv3.mycert.com.br.key

In this case, you need to add the certified to your client

Dockerfile

ENV NODE_EXTRA_CA_CERTS=$project_home/public.crt

Remember to check if you set up everything right inside your container

• echo $NODE_EXTRA_CA_CERTS
• cat $project_home/public.crt
