Create a Flutter gRPC client

In this post, we will address how to create a gRPC client in Flutter and connect to a Server. In order to test our client application, we will quickly build a gRPC service using .Net. gRPC Server (C# .Net) Let us use the Asp.Net core gRPC Service template provided by Visual Studio. With the basic … Continue reading Create a Flutter gRPC client

Generate Password Hash for RabbitMq

In the previous post, we explored how to use docker compose to per-initialize queues in a docker container. The configuration files also provided a way to initialize users. Each of the users where configured with a password, which is given in the configuration file as a hash value comprising of a randomly generated 32 bit salt and … Continue reading Generate Password Hash for RabbitMq

Initialize RabbitMq Docker Container with preconfigured Queues

As we work with docker containers, it is often desired to initialize the containers with specific application needs. One of such requirements was to initialize RabbitMq container with predefined queue. To be more specific, the objective needs to be achieved using docker compose. In this approach, we would use docker volume to map the configurations, which in turn … Continue reading Initialize RabbitMq Docker Container with preconfigured Queues

Retry Pattern

Transient exceptions are a common occurance in the cloud based applications. Most of these temporary faults are self-healing and could succeed when triggered with a slight delay. Some of the common transient errors include momentary loss of connectivity to services, a busy database server that throttle requests to ease off workloads. Ideally an application which … Continue reading Retry Pattern

#DockerDays Day 6 – Docker Compose

Until now, we have learned how to create images using dockerfile and used network to create channels for communicating between two containers. But it can be cumbersome to manage each container separately, particularly in multi-container applications which have dozens of containers. Building, running, and connecting multiple containers using individual dockerfile would be pretty hard and consume a lot of time and … Continue reading #DockerDays Day 6 – Docker Compose

Debugging Wix Installer

How do you debug an installer created using Wix ? This short article shows an easy way to debug your Wix Installer Custom Actions. In fact, it turns out to be pretty easy. All you need to do is to add a call to System.Diagnostics.Debugger.Launch() your custom action. For example, [CustomAction] public static ActionResult DemoMethod() { System.Diagnostics.Debugger.Launch(); … Continue reading Debugging Wix Installer

#DockerDays Day 5 – Building Images with dockerfile

So far we have been downloading images from Docker Hub and running the containers. But how are these images created in the first place? How can we create our own images? In this part of the series of Docker Days, we will delve into building images and how to use the Docker file. Agenda Introduction to dockerfile ?FormatBuild ImageA … Continue reading #DockerDays Day 5 – Building Images with dockerfile

#DockerDays Day 4- Data Persistence

So far we have been mostly interested in running the container, without thinking too much about data. We have also briefly described how the containers add a read-write layer on top of the image's read-only layers while running a container. But what does that actually mean? What happens to the read-write layer when the container … Continue reading #DockerDays Day 4- Data Persistence

#DockerDays Day 3- Networking in Docker

In the previous part of the #DockerDays Series, we learned to run our first container. We also learned how to run a container and connect it from the host machine. As mentioned in the closing comments of the last part, so far we have worked on a single container environment. What happens when you have multiple containers running … Continue reading #DockerDays Day 3- Networking in Docker
