Volumes with symbolic Links not working properly Also another problem might be related with permisions

Description

In my context I got two users and they are being linked. Which are "iotiq"(my user) and "bor".
I am building my containers with a docker-compose.yml.

when I build ngnix with:
`
nginx:
platform: linux/amd64
image: nginx:1.11
ports:
- "80:80"
- "443:443"
volumes:
- "~/..:/home" #PROBLEM
- "./config/nginx-dev:/etc/nginx/conf.d/"
- "/var/log/nginx:/var/log/nginx"
- "/etc/ssl:/etc/ssl" #PROBLEM
depends_on:
- app

`

I am facing with 2 problems. First one is giving No such file or directory:fopen('/etc/ssl/certs/mdm.crt','r'). Which
exists on the host. Container is being exited after docker compose up. Solved with copying ssl directory to my project and gave the copy of "/ssl" as a volume. That solved my problem. I also tried giving 777 to "/etc/ssl" on my host but it didn't work.
Then it started giving "/home/bor/code/mdm_server/assets/ios/blalba does not exist". When I checked with docker exec bash I can see the 2 users inside /home, bor and iotiq. inside of the iotiq I can see all my data since I gave as " ~/..:/home" . But for bor which is linked to the iotiq, only contains /bor/code/mdm_server/ and inside of project is empty. I also dont see my other stuff inside of bor user dir. On my host when I say ls /Users/bor I see all other stuffs in my iotiq user since they are linked. so I gave this as a volume "/Users/iotiq:/home/bor".
Bor is generic user we use in our projects, everything is being based on username bor in other containers as well.

I was using Docker Desktop and it works without problem. Problem with docker desktop is using 6gb for containers and another 8 gb for virtualization :D

configuration belove solved my problem, and it seems colima uses 4gb of rams in total. 😄
I use mongo,grafana,redis,elasticsearch,ngnix,myApp,ldap,mySql with containers

nginx: platform: linux/amd64 image: nginx:1.11 ports: - "80:80" - "443:443" volumes: - "/Users/iotiq:/home/bor" - "./config/nginx-dev:/etc/nginx/conf.d/" - "/var/log/nginx:/var/log/nginx" - "./ssl:/etc/ssl" depends_on: - app

The problem is that Colima by default only mounts your home folder into the vm. Docker runs inside the VM, so it can't find the paths you specified.
In order for Docker to be able to access those folders, you need to mount them into the VM explicitely.
You can configure the mounts in colima.yaml:

mounts:
  - location: /Users   # Assuming you really want to map all User directories into the VM, and not only your current user
    writable: true
  - location: /etc/ssl
    writable: false
  - location: /var/log/nginx
    writable: true

The docker-compose.yml can stay the same.

You can verify if the folders have been mounted into the VM correctly by running colima ssh and then looking for them
