Architecting .NET Applications for Docker and Container Based Deployments
- 1. Architecting .NET Applications for Docker and Container Based Deployments @Ben_Hall Ben@BenHall.me.uk Blog.BenHall.me.uk
- 2. Who? @Ben_Hall Tech Support > Tester > Developer > Founder > Freelancer Ocelot Uproar
- 3. Agenda • What are containers? • .NET running inside a Docker Container • Two Containers • Three Containers • Four Containers, More! • Future of Docker and Windows/.NET
- 4. A Load Balanced ASP.NET Website running inside Docker
- 6. Deployments are hard. They shouldn’t be.
- 8. Container… Own Process Space Own Network Interface Own Root Directories Sandboxed Like a lightweight VM. But it’s not a VM.
- 9. Container… Native CPU Native Memory Native IO No Pre-Allocation Zero Performance Overheard
- 12. Build, Ship and Run Any App, Anywhere Docker - An open platform for distributed applications for developers and sysadmins.
- 14. In Real Life? Digital Ocean Ubuntu Droplet Node.js Node.js GoLang Mono Static Site ElasticSearch ElasticSearch Logstash Kibana Nginx Redis
- 15. - Easy deployment - Isolated sandboxes - Portability - Development === Production - Control
- 18. Production
- 20. Not much .NET on there… At the moment they’re based on Linux. Today Mono works, as does XSP and ASP.NET vNext. Tomorrow?
- 24. .NET APPLICATION RUNNING INSIDE CONTAINER
- 25. $ docker run Usage: docker run [OPTIONS] IMAGE [COMMAND] [ARG...]
- 26. $ docker run --name === Friendly name --rm === Remove when finished -t === Attach to terminal -I === Interactive
- 27. ASP.NET Example
- 29. Dockerfile
- 34. $ docker search
- 35. Dockerfile – ADD / WORKDIR / RUN
- 37. Dockerfile – CMD / ENTRYPOINT
- 39. $ docker build --t === Friendly name. <Docker Hub Username>/<ProjectName>
- 40. $ docker images
- 43. $ docker run
- 44. $ docker ps -a === Show all containers
- 45. $ docker logs -f === tail the logs – watch them in real time
- 46. $ docker run –p $CONTAINERPORT
- 47. Why “$ curl 0.0.0.0:49218” ?
- 48. $ boot2docker ip
- 49. $ curl b2d:49218
- 52. $ docker push
- 55. $ docker export / save
- 56. $ docker import / load
- 57. What do we have? $ cd ~/SourceControl/HelloWorldVNext $ cat Dockerfile $ docker build -t benhall/aspnetvnext . $ docker run -d -t -i -p 5000:5000 benhall/aspnetvnext $ curl 192.168.59.103:5000 <h1>Hello from Razor!!<h1> <h2>From 95a28c090686</h2> $ docker push benhall/aspnetvnext
- 58. TWO CONTAINERS
- 59. Storing Data - Volumes -v /opt/docker/scrapbook_elasticsearch:/data -v /opt/docker/mysql:/var/lib/mysql -v /docker/scrapbook/uploads:/app/public/uploads
- 61. $ docker run –link CONTAINER:ALIAS
- 63. Two Websites On Port 80?
- 64. Nginx
- 68. DockerGen Generate files from docker container meta-data https://github.com/jwilder/docker-gen
- 73. THREE CONTAINERS
- 74. Fig
- 76. $ fig up
- 78. FOUR AND MORE!
- 81. 1) Like DockerGen, Consul raises events on docker events 2) Registrator adds new containers details into Consul 3) Consul links containers IP / Ports to DNS names
- 82. $ ping redis.service.east-aws.consul $ ping redis.service.consul [tag.]<service>.service[.datacenter][.domain]
- 85. BRING IT BACK TO .NET
- 86. How should the app be structure?
- 87. DOCKER AND AZURE
- 88. $ azure vm docker create -e 22 -l 'West US' ubuntu-docker "b39f27a8b8c64d52b05eac6a62ebad85__Ubuntu-14_04-LTS-amd64- server-20140618.1-en-us-30GB" rgardler 1234abcdE$ http://msopentech.com/blog/2014/09/11/docker_host_in_azure/
- 89. $ docker --tls -H tcp://ubuntu-docker.cloudapp.net:4243 info http://msopentech.com/blog/2014/08/15/getting_started_docker_on_microsoft_azure/
- 90. $ docker --tls -H tcp://ubuntu-docker.cloudapp.net:4243 run -t -i ubuntu bash http://msopentech.com/blog/2014/08/15/getting_started_docker_on_microsoft_azure/
- 92. THE FUTURE?
- 93. Docker and Microsoft Partnership
- 94. SQL Server as a Container?
- 96. Visual Studio as a Container?
- 98. IN SUMMARY…
- 99. Only tool I use for deployment • Close gap between development and production • Everything is a container! • Running platforms like Logstash, ElasticSearch, Redis, EventStore, RavenDB, NancyFX etc? Consider containers for deployment.
- 101. THANK YOU @Ben_Hall Ben@BenHall.me.uk Blog.BenHall.me.uk
