serilog-docker

A docker image for testing Serilog on *nix platforms. Also some sample apps.

PreReqs

• Docker (easiest with Docker Toolbox or Docker Beta)

Serilog

• Clone this repo.
• Run docker-compose build to:
  • pull the images
  • build a docker image
• Run docker-compose up to:
  • pull the Serilog repo,
  • build and test the lastest dev branch code from https://github.com/serilog/serilog.
• To enter the container with out using compose, use docker run -it --entrypoint=/bin/bash serilog

Run the Samples

This repo also contains the following samples

• Console App
• Web App
• FSharp Web App

To run these, run docker-compose -f samples.yml up --build

This will

• Build & run the sample docker images.
• The console app periodically does a HTTP GET to the
  • C# Kestrel Sample
  • F# Kestrel Sample
• The console app also logs to the Literate and Splunk sinks.
• The web apps are also configured to use Serilog via Microsoft.Extensions.Logging & Serilog.Extensions.Logging.

Start-Service docker

Run the Samples

This repo contains the following windows samples

• Seq Event Server, based on Windows Server 2016 Server Core image
• Web App, based on Windows Server 2016 Nano Server image

To run these, run docker-compose -f samples-windows.yml up

Containers use nat network. To inspect what IPs they got run docker network inspect nat in the separate cmd shell and find your containers:

"Containers": {
