Review comment:
Hi @ashb , I have checked on another server.
## Without Tag
```python
import docker
client = docker.APIClient(base_url='unix://var/run/docker.sock')
client.create_container(image="fake_image")
```
**Result:**
```
ImageNotFound: 404 Client Error: Not Found ("No such image:
fake_image:latest")
```
## With Tag
```python
import docker
client = docker.APIClient(base_url='unix://var/run/docker.sock')
client.create_container(image="fake_image:version_1")
```
**Result:**
```
ImageNotFound: 404 Client Error: Not Found ("No such image:
fake_image:version_1")
```
## Conclusion
So as I shared earlier: if tag is omitted for `image`, "latest" will be used
by default; if tag is provided by user, then that tag will be used.
So here in `DockerOperator`, we don't need the a few lines I removed.
