[Dimitri2020007]

1. Caddy version (caddy version):

v2.4.3 h1:Y1FaV2N4WO3rBqxSYA8UZsZTQdN+PwcoOcAiZTM8C0I=

2. How I run Caddy:

Cloud Application Platform | Heroku

install caddy bin

a. System environment:

alpine:edge
dockerfile deploy container

b. Command:

/usr/local/bin/caddy run --config /etc/caddy/Caddyfile --adapter caddyfile

c. Service/unit/compose file:

FROM alpine:edge

RUN  apk update && \
     apk add --no-cache --virtual .build-deps ca-certificates nss-tools curl && \

3. The problem I’m having:

error obtaining home directory, please define environment variable HOME.

4. Error messages and/or full log output:

{“level”:“warn”,“ts”:1629167856.1931417,“msg”:“unable to determine directory for user configuration; falling back to current directory”,“error”:“neither $XDG_CONFIG_HOME nor $HOME are defined”}
Error obtaining home directory, please define environment variable HOME.

5. What I already tried:

using caddy version v2.3 ~ v2.1

Still prompted Error obtaining home directory, please define environment variable HOME.

6. Links to relevant resources:

[matt (Matt Holt)]

This means the $HOME environment variable isn’t set.

You can verify this easily enough. What is the output when you add the --environ flag to your run command?

[Dimitri2020007]

$home variable set to caddy work folder or caddy webroot folder ?

I strongly recommend using our official Docker image, which is properly set up. See it on Docker Hub

Try adding the following code in the dockerfile (in addition, please use the official docker image as much as possible. It is not a good idea to run v2ray and caddy in the same docker container).

祝你好运

# See https://caddyserver.com/docs/conventions#file-locations for details
ENV XDG_CONFIG_HOME /config
ENV XDG_DATA_HOME /data

[Dimitri2020007]

XDG_CONFIG_HOME & XDG_DATA_HOME error clear.
but still prompted variable HOME error

[Dimitri2020007]
