Test environment with Docker containers

Pre requirements

You need docker to be installed on your machine. Tested both on Windows and Linux.

Installation

Run this in your package manager console:

 Install-Package TestEnvironment.Docker

To add container specific functionality for MSSQL, Elasticsearch or MongoDB:

 Install-Package TestEnvironment.Docker.Containers.Elasticsearch
 Install-Package TestEnvironment.Docker.Containers.Mssql
 Install-Package TestEnvironment.Docker.Containers.Mongo
 Install-Package TestEnvironment.Docker.Containers.Mail
 Install-Package TestEnvironment.Docker.Containers.Ftp
 Install-Package TestEnvironment.Docker.Containers.MariaDB
 Install-Package TestEnvironment.Docker.Containers.Postgres

Example

// Create the environment using builder pattern.
var environment = new DockerEnvironmentBuilder()
    .AddContainer("my-nginx", "nginx")
    .AddElasticsearchContainer("my-elastic")
    .AddMssqlContainer("my-mssql", "HelloK11tt_0")
    .AddPostgresContainer("my-postgres")
    .AddFromDockerfile("from-file", "Dockerfile", containerWaiter: new HttpContainerWaiter("/", httpPort: 8080))
    .Build();

// Up it.
await environment.Up();

// Play with containers.
var mssql = environment.GetContainer<MssqlContainer>("my-mssql");
var elastic = environment.GetContainer<ElasticsearchContainer>("my-elastic");
var postgres = environment.GetContainer<PostgresContainer>("my-postgres");

// Down it.
await environment.Down();

// Dispose (remove).
environment.Dispose();

Troubleshooting

In case of unpredictable behaviour try to remove the containers manually via command line:

 docker rm -f (docker ps -a -q)

If you use AddFromDockerfile() then it is recommended to prune images time to time:

 docker image prune -f

Ideally, use the --filter option on the docker image prune commandline task. Simply add LABEL "CI_BUILD=True" in your Dockerfile, and force delete all images with that LABEL:

 docker image prune -f --filter "CI_BUILD=True"

Release Notes

• Implement IAsyncDisposable interface.
