This started as a very basic HTTP server which I regularly use to debug HTTP-Clients, Loadbalancers and so forth.

For version 0.1.x I started to cleanup the code and make the configuration more versatile. See http-server -h for available options.

http-server [OPTIONS] [CONFIG]

• Accept requests on 0.0.0.0:80 and return

http-server

• Listen on port 8080:

http-server -addr :8080

By default the server just returns the status code 200 and sends ok in the response body. But you can configure in detail what action should be performed.

There are two things you can configure for each path:

• A number of middleware
• One handler

A request then runs through each middleware in the order in which the middlewares are specified and at the end a handler produces the response. In the following example a request would first run through the log and json middleware and then the static handler would produce the response.

http-server log json static

It's recommended to always use single quotes for the config. They are not needed but if you later use more complex configurations the quoting of the shell can easily mess up your configuration.

You can specify a paths as follows. In the following example requests to /info would run through the log middleware and then the info handler would return some information about the host and the request. Every other request (/) would be sent through the log middleware and then return the static handler would return a static response (ok).

http-server '/info: log info /: log static'

You can also configure the indidual handlers. The following example returns foo on the path /foo and a 404 not found error with the text here is nothing on every other path.

http-server '/foo: log static{body: foo} /: log static{body: "here is nothing", code: 404}'

If you enable TLS the http-server changes it's default port to :443.

If you use the -tls-hosts option the server will automatically perform the ACME with Let's Encrypt for the specified hosts:

http-server -tls-hosts www.myhost1.com,myhost1.com

Generate TLS certificate and key:

oenssl req -x509 -newkey rsa:4096 -keyout tls.key -out tls.crt -days 365 -nodes -subj '/CN=simple-server' -extensions v3_req -config <( echo -e "[req]\ndistinguished_name=req\n[v3_req]\nsubjectAltName = @alt_names\n[alt_names]\nDNS.1 = localhost\nDNS.2 = simple-server.local\nIP.1 = 127.0.0.1" )

Alternatively you could use pcert to create a certificate in a much simpler way:

pcert create tls --subject "/CN=simple-server" --dns localhost --dns simple-server.local --ip 127.0.0.1

And then use the following options:

http-server -tls-cert tls.crt -tls-key tls.key

• Run

docker run -p 8080:8080 --rm dvob/http-server
