QUESTION
I have been going for hours trying to understand why docker just so happen to doesn't work on my machine. I am using Ubuntu 18.01 Xfce. Have installed docker using the official site and tried to test run an image using docker container run -it -p 8000:80 nginx command. The first it ran ok, but only I try another time the localhost goes into an endless loop of loading. It only works after I restart docker and then only the first time. I also tried editing docker.service file into:

...ANSWER
Answered 2019-Oct-17 at 21:13Even if you configure MySQL to listen on all interfaces, and then from your container access MySQL from a non-loopback IP, you may find that Docker’s routing, NAT, and firewall rules do not allow you to access services running on the host. The fast workaround for this is to run your container on the host network stack with:

I've created an Oracle service to return a random dice roll and sign a transaction including that data. The Oracle keeps track of the unique identifier of a specific state and will only create a random dice roll once for any given UUID.
When I trigger the initial flow, which should send and receive data with the Oracle - I get this error.
Here is the link to the repo: https://github.com/rogersanick/SettlersOfCordan
Steps to reproduce
Open the project (do not import)
Run the test - oracleReturnsARandomDiceRoll in the oracleClient/src/test directory (make sure you include -ea -javaagent:PATH/TO/QUASAR.jar in the runtime config)

I'm trying to test the flow, specifically when an exception is thrown, but for some reason I'm not getting anything in the errorsFromSend channel.
Here is the gateway:
...ANSWER
Answered 2018-Dec-14 at 22:04Caused by: org.springframework.messaging.MessageHandlingException: nested exception is java.lang.RuntimeException: xyz, failedMessage=GenericMessage [payload=xyz, headers={errorChannel=errorsFromSend, id=38b35bcb-61f1-7be4-c523-499d8fa13db7, timestamp=1544808482872}]
Since the failed message has the error channel header; it should have been routed properly by the error handler in the poller.
If you can post the complete project (perhaps in the Gist, or the complete project in GitHub), we can take a look.
EDIT
It looks like the DSL has a bug, the executor channel is not initialized properly so your task executor is not wrapped in an ErrorHandlingTaskExecutor.
Here is a work-around:

I'm working with Docker 1.12.5 on macOS 10.12, and am setting up a development environment with with I have an application image, and a shared redis image which has some pre-populated configuration variables.
Even after following a few tutorials (and reading about how docker0 isn't available on Mac) I'm struggling to connect the two containers.
I start my redis image using:
ANSWER
Answered 2017-Jan-04 at 19:13Each service runs in its own container. From the perspective of the Ubuntu container, redis is not listening on localhost.
Use Docker networksTo get your containers to communicate, they should be on the same Docker network. This consists of three steps:
- Create a Docker network
- Give your containers names
- Attach your containers to the network you created
With this done, the containers can talk to each other using their names as if they were hostnames.
There's more than one way to skin this cat... I will look at two in this answer, but there are probably a few other ways to do it that I am not familiar with (like using Kubernetes or Swarm, for instance).
Doing it by handYou can create a network for this application using docker network commands.

Answered 2018-Apr-04 at 15:20Firebase cannot perform a query across array members, to see if it contains a specific value in any position or to add/remove a record.
Note, that Firebase documentation recommends against using arrays. One of the many reasons Firebase recommends that is that it makes the security rules impossible to write.
As usual with NoSQL databases, I will suggest you an alternative structure like this:
