QUESTION
I've been implementing feature file tests for a microservice in Golang using Godog.
There are 54 steps in my feature file and I generated the step definitions for all of them.
When I run the test using go test
command, the first 22 scenarios pass and the 23 is declared as Undefined
even though its definition is present.
My Console output after any test:
...ANSWER
Answered 2021-May-25 at 06:51It turns out Godog doesn't trim the Steps from the feature
files.
So, In my feature files, the steps for the above lines included:
When reading resource of id "ID1"_____(blank space)
The regex pattern therefore wasn't able to map the step definitions to these lines for some reason.
As soon as I removed the empty spaces, it worked great.

ANSWER
Answered 2020-May-21 at 23:59Its a bug with version inconsistency between go-micro and grpc. About a week ago I tried to follow the tutorial which you mention and got same error. If you want to fix the error above please follow the interactions below the link: https://github.com/etcd-io/etcd/issues/11563.
In additionally I recommend you just build grpc service without go-micro, due to version inconsistency.
QUESTION
I'm writing my first Rust
microservice with hyper
. After years of development in C++
and Go
I tend to use controller for processing requests (like here - https://github.com/raycad/go-microservices/blob/master/src/user-microservice/controllers/user.go) where the controller stores shared data like db connection pool and different kinds of cache.
I know, with hyper
, I can write it this way:

always acquires a (compile time or runtime) exclusive lock to the value.
Only acquire a &mut
at the exact scope you want to get locked.
If a value owned by the locked value needs separate locking management,
wrap it in a Mutex
.
Assuming your DbConnectionPool
is structured like this:

I am trying out go-micro and I have issues genearating .micro
boilerplate code. I have set my env and even passed the direct directory of my GOPATH

I think you omitted the second step.

QUESTION
I'm developing a Django (2.2.3) application with Django Microsoft Auth installed to handle SSO with Azure AD. I've been able to follow the quickstart documentation to allow me to log into the Django Admin panel by either using my Microsoft identity, or a standard username and password I've added to the Django user table. This all works out of the box and is fine.
My question put (really) simply is "What do I do next?". From a user's perspective, I'd like them to:
- Navigate to my application (example.com/ or example.com/content) - Django will realise they aren't authenticated, and either
- automatically redirect them to the SSO portal in the same window, or
- redirect them to example.com/login, which requires them to click a button that will open the SSO portal in a window (which is what happens in the default admin case)
- Allow them to sign in and use MFA with their Microsoft Account
- Once successful redirect them to my
@login_required
pages (example.com/content)
Currently, at the root of my navigation (example.com/), I have this:
...ANSWER
Answered 2020-Feb-03 at 10:30A couple more days at this and I eventually worked out the issues myself, and learned a little more about how Django works too.
The link I was missing was how/where context processors from (third party) Django modules pass their context's through to the page that's eventually rendered. I didn't realise that variables from the microsoft_auth package (such as the authorisation_url
used in its template) were accessible to me in any of my templates by default as well. Knowing this, I was able to implement a slightly simpler version of the same JS based login process that the admin panel uses.
Assuming that anyone reading this in the future is going through the same (learning) process I have (with this package in particular), I might be able to guess at the next couple of questions you'll have...
The first one was "I've logged in successfully...how do I do anything on behalf of the user?!". One would assume you'd be given the user's access token to use for future requests, but at the time of writing this package didn't seem to do it in any obvious way by default. The docs for the package only get you as far as logging into the admin panel.
The (in my opinion, not so obvious answer) is that you have to set MICROSOFT_AUTH_AUTHENTICATE_HOOK
to a function that can be called on a successful authentication. It will be passed the logged in user (model) and their token JSON object for you to do with as you wish. After some deliberation, I opted to extend my user model using AbstractUser
and just keep each user's token with their other data.

QUESTION
I have constructed a "go-micro" service. From what I understand, go-micro uses protobuf to define and create the messages structures & used gRPC as the network protocol (I of course might be wrong here).
If the above it correct, than what does the plug-in "go-grpc" is being used for?
Thanks!
...ANSWER
Answered 2018-Apr-10 at 13:27Go-micro makes use of the Go interface for it’s abstractions. Because of this the underlying implementation can be swapped out. Default go-micro uses HTTP for communication
Go-GRPC is a simple wrapper around go-micro and the grpc plugins for the client and server.

I am trying to figure out how to integrate the gorm.Model fields (deleted_at, create_at, id, etc) into my proto3 definitions. However, I can't a datetime type for proto3. I tried looking for documentation on how to serialize the gorm fields to strings (since proto3 handles strings) but I have not found anything.
Has anyone been able to successfully use the gorm model fields in their proto definitions? I'm using go-micro's plugin to generate *pb.go files.
Here's my current message definition which doesn't work. It seems like empty strings are being stored in the database for deleted_at since when querying for deleted_at is null the postgres database returns nothing.

Answered 2019-Oct-08 at 05:49Try to use protoc-gen-gorm. It will create another file .pb.gorm.go
QUESTION
I am trying to enable communication between Kubernetes (K8s) pods and a Docker container but I cannot find how to do so on Windows. Help would be greatly appreciated.
Scenario description:
The n K8s pods are composed of one (and only) container: a Go microservice accessed by Postman at this time, itself supposed to access a database.
To enable a load-balanced access to the pods as one, a Kubernetes service is put on top, using a NodePort. So far everything is working.
But the K8s-Pod/Go-microservice <> Docker-container/db part do not see each other. The Go microservice obviously says the "db" cannot be resolved. The container db is itself in a user-defined docker network (called "mynw"); its type is a bridge.
Would anyone know how to acheive this in the simplest way? (I mean without third-party/tierce things, heavy proxy configuration, etc.)
Thanks!
...ANSWER
Answered 2019-Sep-22 at 17:58You can create a headless service in k8s, with an endpoint pointing to your database container. Then you have to direct your Go service to use that headless service as the db connection.
