Troubleshooting a local Corda 5 network
ERROR: The Compose file is invalid
If you see this error while trying to use
docker-compose with your generated
.yaml config file, you may have an old version of Docker.
Try to upgrade.
ERROR: The Compose file is invalid because: networks.smoke-tests-network value Additional properties are not allowed ('name' was unexpected)
Mac Docker memory allocation
Docker Desktop for Mac, by default, only assigns two GB of RAM to the Docker daemon. This isn’t sufficient for running a three-node Corda network. You can increase this in the Docker Desktop: go to Preferences and configure Docker Desktop to have at least six GB of RAM and use six cores.
Windows Docker daemon
If you are using Docker on Windows, you may get this error when executing the end-to-end tests:
org.apache.hc.client5.http.HttpHostConnectException: Connect to http://localhost:2375 [localhost/127.0.0.1, localhost/0:0:0:0:0:0:0:1] failed: Connection refused: connect java.lang.RuntimeException: org.apache.hc.client5.http.HttpHostConnectException: Connect to http://localhost:2375 [localhost/127.0.0.1, localhost/0:0:0:0:0:0:0:1] failed: Connection refused: connect at com.github.dockerjava.httpclient5.ApacheDockerHttpClientImpl.execute(ApacheDockerHttpClientImpl.java:153) at com.github.dockerjava.httpclient5.ApacheDockerHttpClient.execute(ApacheDockerHttpClient.java:8) at
This is because we use the Docker Java API to interact with the Docker daemon (Unix sockets are used on Linux and macOS). On Windows you need to expose the daemon on port 2375 explicitly. Go to Settings > General and select the following options:
- Expose daemon on tcp://localhost:2375 without TLS
- Use the WSL 2 based engine
Windows file sharing
If you use Windows, you may see an error like this:

To resolve this, add the path to the File sharing options:
