colima x86_64 daemon.json file has incorrect proxy

[dragonfriend0013]

Description

I use zscaler on my machine (M2 Mac), so my local proxy is set to 127.0.0.1:9000. during the colima start, it set the proxy variable to a 192.* address, but the daemon.json file still shows as the original 127 address. this should be updates with the updated address. i can manually update this through ssh, but it would be better if this is done when colima starts.

docker build does not have this issue, only docker compose and docker-compose

Output of colima status

INFO[0000] colima is running using QEMU
INFO[0000] arch: x86_64
INFO[0000] runtime: docker
INFO[0000] mountType: sshfs

Reproduction Steps

1. colima delete
2. colima start --arch x86_64
3. docker compose up --detach (have an external image that must be pulled through proxy)

Expected behaviour

docker compose works

Additional context

env variable on Mac:
http_proxy=http://127.0.0.1:9000
https_proxy=http://127.0.0.1:9000

env variable on colima
https_proxy=http://192.168.5.2:9000
http_proxy=http://192.168.5.2:9000

I have the same issue with colima 0.6.7. This was working properly until version 0.5.x.

I notice that in the feature list of release 0.6.0 there is this statement:

• Proxy variables HTTP_PROXY, HTTPS_PROXY, NO_PROXY and their lowercase variants are now forwarded to the Docker daemon.

Proxy variables should be taken from inside Qemu and not from the Host, so to get the remapped values (that is 192.168.5.2 instead of 127.0.0.1).

For now I must stay on colima 0.5.6, where I do not have this issue.

[abiosoft]

It is an oversight. 127.0.0.1 proxy host address should be auto-translated to 192.168.5.2.

[fralken]

Is it necessary to set the proxies in daemon.json? In colima 0.5.6 they are not set but docker info shows the values from the env variables.

HTTP Proxy: http://192.168.5.2:8128
HTTPS Proxy: http://192.168.5.2:8128

Any update on getting this corrected?

[hotwebmatter]

This approach worked for me.

Using the provision key in ~/.colima/default/colima.yml:

provision:
  - mode: system
    script: |
      GLOBAL_PROXY='127.0.0.1:9000'
      COLIMA_PROXY=$(echo $http_proxy | sed -e 's/http:\/\///')
      sed -i "s/$GLOBAL_PROXY/$COLIMA_PROXY/" /etc/docker/daemon.json
      systemctl daemon-reload
      systemctl restart docker 

First, this sets $GLOBAL_PROXY to 127.0.0.1:9000 (NOTE: If the correct proxy setting for your host OS differs from this, set this value accordingly.)

Then, it gets the value of $http_proxy from inside the vm (equivalent to colima ssh), strips the leading protocol identifier, and stores it as $COLIMA_PROXY.

Then it finds $GLOBAL_PROXY in /etc/docker/daemon.json and updates that value to match $COLIMA_PROXY.

Finally, it reloads the changes and restarts the Docker daemon. (If the provisioning script were run as a user instead of as mode: system, these last two commands would require sudo.)

Nice!

I'm wondering if you have solved the problem of configuring the proxy in the daemon.json file when you start docker in colima? Every time I modify the daemon.json file to configure proxies, the proxy is not implemented.

[davidolrik]

I too have this issue - and it is not constrained to x86_64.

colima version 0.7.5
git commit: 1588c066b9ab9dae8205ef265929c7eb43dca473

runtime: docker
arch: aarch64
client: v27.2.0
server: v27.1.1

In addition I can't use the workaround due #1060

[rteeling-evernorth]

I've found the issue, documented in #1144

the above PR should fix this, this can be closed
