1. Output of caddy version:
I am unsure, I did not set-up Caddy, our web hosting company set-up and is managing the running of Caddy for us. The only method I have to interface with Caddy is through the API.
2. How I run Caddy:
I am unsure
a. System environment:
I know it is a Linux server but I don’t know beyond that. I could find out this and the version if necessary.
d. My complete Caddy config:
This config is changing fairly regularily as I am currently in the messing about stage.
{
"admin": {
"listen": "lb.madeopen.co.uk:2019"
},
"apps": {
"http": {
"servers": {
"test_srv": {
"listen": [
":443"
],
"routes": [
{
"handle": [
{
"handler": "subroute",
"routes": [
{
"handle": [
{
"handler": "reverse_proxy",
"transport": {
"protocol": "http",
"tls": {}
},
"upstreams": [
{
"dial": "test.yourplatforms.org:443"
}
]
}
]
}
]
}
],
"match": [
{},
{
"host": [
"lb.madeopen.co.uk"
]
}
],
"terminal": true
}
]
}
}
}
}
}
3. The problem I’m having:
I am trying to add a new server to the list of servers through the API. Whatever I do it is replacing the current server config not appending, I am using /… for the config url but with or without that it just replaces the current server config
curl --location --request POST 'http://lb.madeopen.co.uk:2019/config/apps/http/servers/...' \
--header 'Content-Type: application/json' \
--data-raw '{"test_srv":{"listen":[":443"],"routes":[{"handle":[{"handler":"subroute","routes":[{"handle":[{"handler":"reverse_proxy","transport":{"protocol":"http","tls":{}},"upstreams":[{"dial":"test.yourplatforms.org:443"}]}]}]}],"match":[{},{"host":["lb.madeopen.co.uk"]}],"terminal":true}]}}'
The other server config I plan to set-up is:
{"test_new_srv":{"listen":[":443"],"routes":[{"handle":[{"handler":"subroute","routes":[{"handle":[{"handler":"reverse_proxy","transport":{"protocol":"http","tls":{}},"upstreams":[{"dial":"test3.yourplatforms.org:443"}]}]}]}],"match":[{},{"host":["lb.madeopen.co.uk"]}],"terminal":true}]}}
It is worth pointing out that none of the yourplatforms.org sub-domains are setup at the moment, I am literally just trying to append a http server config through the API.
My ultimate end goal in case it is useful is to use Caddy as a reverse proxy to a whole bunch of different client domains and sub-domains. Our clients will be able to set-up domains themselves and then create “platforms” within their account (on our main software) that will use a sub domain. As clients add domains and sub-domains our application will use a DNS API to get the records added and then utilise the Caddy API to add the appropriate records for it all to work. I was planning on using a server per client domain.
4. Error messages and/or full log output:
I am not receiving an error
5. What I already tried:
I did try to be a bit clever and just pass a JSON array of two server configs:
curl --location --request POST 'http://lb.madeopen.co.uk:2019/config/apps/http/servers/' \
--header 'Content-Type: application/json' \
--data-raw '[{"test_new_srv":{"listen":[":443"],"routes":[{"handle":[{"handler":"subroute","routes":[{"handle":[{"handler":"reverse_proxy","transport":{"protocol":"http","tls":{}},"upstreams":[{"dial":"test3.yourplatforms.org:443"}]}]}]}],"match":[{},{"host":["lb.madeopen.co.uk"]}],"terminal":true}]}},
{"test_srv":{"listen":[":443"],"routes":[{"handle":[{"handler":"subroute","routes":[{"handle":[{"handler":"reverse_proxy","transport":{"protocol":"http","tls":{}},"upstreams":[{"dial":"test.yourplatforms.org:443"}]}]}]}],"match":[{},{"host":["lb.madeopen.co.uk"]}],"terminal":true}]}}
]'
Which results in the following error and I suspect I am using the API incorrectly here:
{
"error": "loading new config: loading http app module: decoding module config: http: json: cannot unmarshal array into Go struct field App.servers of type map[string]*caddyhttp.Server"
}
