sam build --use-container failed mounting directory - amazon-web-services

Question

There was no issue in building the project a little while back, but it started throwing below error.
RuntimeError: Container does not exist. Cannot get logs for this
container
Normally this happens when docker cannot mount the shared directory, but in this case even adding the lambda directory manually in the docker interface didn't help!

Answer 1

In my case the reason was different, Action Center's Focus Assist was set to Alarms Only.
This caused the share directory notification to fail, causing the build failure.
So, make sure your Focus Assist is set to OFF.

Answer 2

It seems that many situations can trigger the same error. For more information the --debug option can be used like this:
sam build --use-container --debug
I see that you are using it, because you got extra information like this:
Sending Telemetry: {'metrics': [{'commandRun': {'awsProfileProvided': False, 'debugFlagProvided': True, 'region': '', 'commandName': 'sam build', 'duration': 1292, 'exitReason': 'RuntimeError', 'exitCode': 255, 'requestId': 'cbfcd29c-16ae-xxxx-xxxx-b9ffec8de75a', 'installationId': 'fece8ccc-cb84-xxxx-xxxx-ac72820ef0c3', 'sessionId': 'e1cbc287-1850-xxxx-xxxx-3a235769f7fb', 'executionEnvironment': 'CLI', 'pyversion': '3.7.6', 'samcliVersion': '0.53.0'}}]}
HTTPSConnectionPool(host='aws-serverless-tools-telemetry.us-west-2.amazonaws.com', port=443): Read timed out. (read timeout=0.1)
Traceback (most recent call last):
In my case I did suppose that the error was sending the telemetry.
My guess is that somehow the build process need pass the region. In my case it is not us-west-2.
Anyway, I disabled it as specified in the documentation and it now works.

Answer 3

In my case local disk in my cloud9 was almost full, so I had to delete some docker images that comes pre-installed with cloud9.
To remove an image use
docker rmi Image
This will clear up space and your build will not fail the next time.
