How to load Environment Variables on running with systemd

[cospotato]

version: 3.0.0

I have running coder-server with this code-server.service

[Unit]
Description=Code Server
Wants = network-online.target
After = network.target

[Service]
Type=simple
EnvironmentFile=/root/.env
ExecStart=/usr/local/bin/code-server --host 0.0.0.0 --port 65535 --auth none
KillMode=process
Restart=on-failure
RestartSec=10s
StandardOutput = syslog

[Install]
WantedBy=multi-user.target

The /root/.env is

HOME=/root
GOCACHE=$HOME/.cache/go-build

But I still got error like this

go.toolsGopath setting is not set. Using GOPATH /root/go

How to figure this out?

Thanks

Thanks for this! Very helpful

@cospotato Hello, any idea how i can export my shell variables.
My shell is zsh, so I tried to set

EnvironmentFile=/home/lest/.zshrc

but it is not working. In the integrated shell, the env is not the same as in my shell.

[jsjoeio]

Hmm...maybe you need to check your .zshrc file and make sure zsh sees it? I was able to get it working myself:

1. Open ~/.zshrc file
2. Add environment variable: export HEY="Hey Lestt!"
3. Restart code-server
4. Run echo $HEY in integrated terminal and see output

It may also be worth revisiting the ZSH docs.

@jsjoeio You're right, a typo from my side.
Thanks mate, works well !
