Functions from the 'strings' package as template actions. Feel free to copy+paste into your project as a starting point.
View stringscontext.go
// Functions from Go's strings package usable as template actions
// with text/template.
// This approach assumes you have some context type as a receiver,
// but if you just need the functions check out the FuncMap variant
// below.
// Commented functions are not deemed useful in template actions.
// Haven't actually used this, but this is one possible way of doing it.
// Another option is to fill a FuncMap with most of the strings package.

Using runit as a supervisor for Caddy


A supervisor's main task, is to start a specified process (in a specified environment), watch it running, and do something when it ends - usually based on the exit code.


From my experience, the environment setup can be a complex task (consult some config management for the required ports, actualize the config file from the central config management...), and this is where the most featureful supervisor (systemd, AFAIK) falls short:

  • it can setup & manage the listening sockets, and pass it to your app (if it can accept it - not hard, just have to be ready for it),

config_server "https://etcd.local:2379"
service users {
endpoint: "/users",
proxy: "{{services.users.ip}}:{{services.users.port}}"
# In this example 'services.users' would be a directory with a json key for every user service container / application.
# Using this we could template the proxy and any other information in the services block, and it would just work with caddy.

Is it necessary to consume response body before closing it (net/http client code)?

When using http.Get(), is it really necessary to read the full response body just to close it later?
The docs keep saying `Caller should close resp.Body when done reading from it.` and I keep seeing code like this:
io.Copy(ioutil.Discard, resp.Body)
