Fnginx DockerFile (Flask & Nginx)

In order to meet the need of serving static html files and dynamic python web-services having flask and nginx on one machine is more efficient than rendering static html file in python embeded code in Flask or any framework.

Build and run

• docker build -t name/tag .
• docker run -d -p 80:80 name/tag

Write your web-service

/app directory contains sample flask app routed to /service with just a welcome message return. You can fork this repo and more complex web-services that can return dynamic responses.

Proxy Tips

• Behind proxy DNS server to 8.8.8.8 in default vm of docker where docker host runs
• And set http_proxy and https_proxy
• While behind proxy remove those (commented ‘em)

How to delete all docker images at once.

• docker images | grep -vi image | awk '{print $3; cmd="docker rmi -f " $3; system(cmd)'}

How to delete all containers

• docker ps | grep -vi container | awk ‘{print $1; cmd=“docker kill “ $1; system(cmd)’}

How to run docker-daemon behind proxy. (On Mac-Os X)

• docker-machine ssh default
• sudo vi /var/lib/boot2docker/profile add following lines. export HTTP_PROXY=http://your.proxy.name:8080 export HTTPS_PROXY=http://your.proxy.name:8080
• docker-machine restart default

Run docker-daemon behind proxy (on Ubuntu)

• Add following line in /etc/default/docker export HTTP_PROXY=http://your.proxy.name:8080 export HTTPS_PROXY=http://your.proxy.name:8080 DOCKER_OPTS="--dns-search --dns --dns --dns "

Adding proxy as ENV in your docker file. (So that docker image can talk to out side www)

• You may also want to consider adding proxy settings in the docker image. ENV HTTP_PROXY 'http://your.proxy.name:port#' ENV HTTPS_PROXY 'https://your.proxy.name:port#'

Note: Remember on mac osx docker-machine has different architecutre since small kernel based VM is the running in virtual box along with docker deamon. Hence docker-machine and docker commands on your os-x are clients where as 'default' light weight VM is the server. And that server has to set the proxy in /var/lib/boot2docker/profile
