🐛 Docker command does not load as an array

[mike548141]

Describe the bug
container fails to load the binary and parameters when I use a YAML array for command:

I use docker-compose to create stacks of containers, I have templated how I layout networks, services etc... I use a YAML array for the command: section because some containers (like Traefik) have a lot of command parameters, and generally it makes the YAML easier to manage.
I've not had issues with that with any other container but cloudflared does not like it. The full command is shown in the container details but the logs show the binary is outputting a help screen of the parameter options to load it properly.

To Reproduce
This compose works as expected
services: cloudflared: container_name: cloudflared command: tunnel --no-autoupdate run --token-file /run/secrets/cloudflare_tunnel_token image: cloudflare/cloudflared:latest networks: dmz: proxy_in: restart: unless-stopped security_opt: - no-new-privileges=true secrets: - cloudflare_tunnel_token

This compose does not load the binary in the container, logs show the help screen
services: cloudflared: container_name: cloudflared command: - tunnel - --no-autoupdate run - --token-file /run/secrets/cloudflare_tunnel_token image: cloudflare/cloudflared:latest networks: dmz: proxy_in: restart: unless-stopped security_opt: - no-new-privileges=true secrets: - cloudflare_tunnel_token

Container details shown in Portainer
ENTRYPOINT cloudflared --no-autoupdate
CMD tunnel --no-autoupdate run --token-file /run/secrets/cloudflare_tunnel_token

Expected behavior
Docker does render/understand the YAML array, if I look at the container it shows the command with all the parameters formatted the same as without the YAML array. I would expect cloudflared to load properly with or without using a YAML array.
