How to apply registry-mirrors in rancheros?


I come from China!
Docker is blocked by the national firewall,so downloading images is slow.In ubuntu 16.04,I use sudo tee /etc/docker/daemon.json <<-‘EOF’
“registry-mirrors”: [“”]
EOF, is for speeding-up.
and then sudo systemctl restart docker,
it works,but using it in rancheros, it works for docker ,not for system-docker,so i can’t pull the images,the speeding-up does not work.Need a lot of time to download and lead to failure.SO what should i do to make “system-docker pull XXX” works and should use what commnads to make it work at once and do not need to reboot the rancheros.
I make it clear? Anyone can help,thank in advance.


Yes clear what you want.

How are registry mirrors added to System Docker?

According to that document linked above, you should do this instead of what you are currently doing (I’ve not tested, only interpreting the docs to what should work)

    registry_mirror: ""
    registry_mirror: ""

Hope this works for you


According to your advice,I use(I have installed the rancheros already):
sudo ros config set rancher.docker.registery_mirror
sudo ros config set rancher.system_docker.registery_mirror ,
but it does not work at once,when I reboot the rancheros,it works.
So the question is how to make it work at once and don’t need to reboot the rancheros???


So instead of running the commands, put the actual cloud config posted in your cloud-config.yml :slight_smile:


following Install to Disk docs,

$ sudo ros install -c cloud-config.yml -d /dev/sda
INFO[0000] No install type specified...defaulting to generic
Installing from rancher/os:v0.5.0
Continue [y/N]:

update this cloud-config.yml specified to include

    registry_mirror: ""
    registry_mirror: ""

These settings need to be set when docker/system-docker is started, there is no way to alter at runtime by the looks.


I know your meaning,thanks a lot.


Did you try to do it in 2 steps using the docker instructions:


When you use the RancherOS registry-mirror config, it does the rest for you - all in one step.



I have the same configuration :

    registry_mirror: "https://docker-public.recette.local"
    registry_mirror: "https://docker-public.recette.local"
      auth: == 

but when I docker search it fails :

[rancher@rancheros1 ~]$ docker search debian
Error response from daemon: Get dial tcp i/o timeout

My proxy is working, but I need to specify it :

rancher@rancheros1  ~]$ docker search docker-public.recette.local/debian

any idea ?


docker search docker-public.recette.local/debian? docker-public.recette.local/debian
is a local repository? if so,registry_mirror: "https://docker-public.recette.local"
registry_mirror: “https://docker-public.recette.local”,it does not work,you understand wrongly,should use insecure-mirror
