No Docker client strategy found-CodePudding

I'm trying to implement E2E testing in NestJS application. I'm using Postgres in a docker container. It is running fine for other testing. The only problem is E2E testing. And I'm getting the following error:

    No Docker client strategy found

      at node_modules/testcontainers/dist/docker/docker-client.js:46:11
      at fulfilled (node_modules/testcontainers/dist/docker/docker-client.js:5:58)

      63 |   });

My code is given below:

describe('EventAPI (e2e)', () => {
  jest.setTimeout(180_000);
  let app: INestApplication;
  let service: Service;
  let container: E2EPgContainer;

  beforeAll(async () => {
    container = new E2EPgContainer();
    await container.init();

    // eslint-disable-next-line @typescript-eslint/no-var-requires
    const AppModule = require('../src/server/app/app.module').AppModule;
    const module: TestingModule = await Test.createTestingModule({
      imports: [AppModule],
    }).compile();

    app = module.createNestApplication();
    app.useGlobalPipes(new ValidationPipe({ transform: true }));
    service = module.get<Service>(Service);
    await app.init();
  });
  afterEach(() => {
    jest.clearAllMocks();
  });

  afterAll(async () => {
    await app.close();
    await container.stop();
  });

  describe('GET-POINT API', () => {
     it('GET /:customerId --> should return success 200 after get points', async () => {
        // test code
     });
  });
});

How can I solve this issue?

CodePudding user response：

I'm assume that your docker container is running, but not as rootless. Make sure you are running your docker as rootless. You can try following:

$ sudo groupadd docker
$ sudo gpasswd -a $USER docker

Now make sure the following environment variables are set (or add them to ~/.bashrc)

export PATH=/home/ubuntu/bin:$PATH
export DOCKER_HOST=unix:///run/user/1001/docker.sock

Now try to restart docker

$ sudo service docker restart

After all steps try following docker command in terminal without sudo:

$ docker ps

If you are able to see your docker container, then it will solve your problem.
