I have two virtual machines: one with microk8s and another without microk8s. In order to build containers, I use the Microk8s registry to save my docker image. To ahieve this, I execute this commands:
microk8s enable registry
docker build . -t dirIPoftheVM:32000/vnf-image:registry
echo '{"insecure-registries": ["dirIPoftheVM"]}' | sudo tee /etc/docker/daemon.json
sudo service docker restart
docker push :32000/vnf-image:registry
In the other machine, I execute:
docker run dirIPoftheMV:32000/vnf-image:registry
and it returns the following error:
docker: Error response from daemon: Get "https://dirIPoftheVM:32000/v2/": http: server gave HTTP response to HTTPS client
How can I solve this?

When I run this command:
docker-compose pull --quiet --ignore-pull-failures
I get this error:
ERROR: Get "https://registry-1.docker.io/v2/": Bad Gateway
This was working fine before but it suddenly stopped working.
Is this docker issue ?
It happens sometimes!
Docker is not working at that time. You should restart your docker server. If you’re in windows and have a docker engine installed restart it manually by clicking on the docker icon on the bottom right then restart docker.
Or try the following command
service docker restart
docker pull...
If you are on linux based machine try the following command:
$ sudo systemctl daemon-reload #THIS IS RESCUE COMMAND…
$ sudo systemctl restart docker
$ sudo systemctl status docker
$ docker pull ...
Note : Try to log out and then login before executing the commands.
docker logout
docker login
you may also need to try connecting docker VM to direct internet connection without any firewall.
sudo docker ... works.
Maybe its firewall issue, but I am not sure
I installed a Docker registry to my server like below;
docker run -d -p 5000:5000 --name registry registry:2
So after that I pushed Alpine image to that registry.
docker pull alpine
docker image tag alpine localhost:5000/alpinetest
docker push localhost:5000/alpinetest
So the problem is I want to access this image from another server.
So I can run the command below from client to Docker registry's server;
user#clientserver ~
$ curl 10.10.2.18:5000/v2/_catalog
{"repositories":["alpinetest"]}
So how can I pull this "Alpinetest" image from another "clientserver"?
For example the command below is not working;
user#clientserver ~
$ docker pull 10.10.2.18:5000/alpinetest:latest
Using default tag: latest
Error response from daemon: Get "https://10.10.2.18:5000/v2/": http: server gave HTTP response to HTTPS client
Thanks!
On the machine that wants to pull the image, create or edit /etc/docker/daemon.json and enter this:
{
"insecure-registries": ["10.10.2.18:5000"]
}
and then run:
sudo systemctl restart docker
Just be aware that the registry is, just like it says, insecure. This setup shouldn't be used when the registry is accessed over the internet or in any other environment that you don't have full control over. But it's definitely nice for local tests.

Issue:
My company uses a transparent proxy with an intermediate cert to navigate. I was able to install the cert following doc: https://docs.docker.com/ee/dtr/user/access-dtr/ and these steps:
# Download the DTR CA certificate
sudo curl -k https://<dtr-domain-name>/ca -o /etc/pki/ca-trust/source/anchors/<dtr-domain-name>.crt
# Refresh the list of certificates to trust
sudo update-ca-trust
# Restart the Docker daemon
sudo /bin/systemctl restart docker.service
Curl and Wget are working well, but docker run is not:
bash $ docker run -it cheers
Unable to find image 'cheers:latest' locally
docker: Error response from daemon: Get https://registry-1.docker.io/v2/: remote error: tls: handshake failure.
See 'docker run --help'.
I've tried adding the registry as insecure in daemon.json but it was unsuccessfully.
Has anyone run into the same problem?
I think i figured out what’s going on:
Docker client offers only TLS_ECDHE_* ciphers but .docker.io (behind my corporate proxy) offers only TLS_RSA ciphers.
Without proxy, docker.io offers both types of ciphers.
Now, next challenge: make docker offer TLS_RSA or make my proxy support TLS_ECDHE.
I have no idea how to do either :frowning:
I have a Red Hat machine on an AWS cloud. I installed Ansible and Docker (experimental version as the community edition cannot be installed now on Red Hat). Now I am runnig a simple command to check whether Docker works:
ansible local -m shell -a "docker pull hello-world"
I'm getting the following error:
localhost | FAILED | rc=1 >>
Using default tag: latest
Warning: failed to get default registry endpoint from daemon (Cannot connect to the Docker daemon. Is the docker daemon running on this host?). Using system default: https://index.docker.io/v1/Cannot connect to the Docker daemon. Is the docker daemon running on this host?
When I use
sudo ansible local -m shell -a "docker pull hello-world"
localhost | UNREACHABLE! => {
"changed": false,
"msg": "Failed to connect to the host via ssh: Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password).\r\n",
"unreachable": true
}
I have tested Ansible by copying a file into local host and it works fine whereas with Docker I'm facing this issue. Is there anything I am missing or anything that needs to be setup for Docker's experimental version?
You don't want to run ansible through sudo but tell ansible that it should run the command using sudo. That can be done by adding the -s flag
ansible local -s -m shell -a "docker pull hello-world"
I try to Install Stratos with Kubernetes in a Testing Environment to build Stratos.I downloading the Kubernetes binaries and provisioned a Docker registry to VAGRANT_KUBERNETES_SETUP folder (in 2.c. i in page).But it gives 3 Failed Units(docker.service,setup-network-environment.service and docker.socket) When I Log into the master node.So I can't view Docker images by using 'docker images' command.when I view docker images it give this error-"FATA[0000] Cannot connect to the Docker daemon. Is 'docker -d' running on this host?" how can i fixed this problem?do i need to install in different way to work with vagrant?
Did you do a sudo -s on the node ? You have to be an admin to connect to the docker daemon and do queries using docker command line client.
