I am using Linux and trying to simulate a ibm mq server by myself via podman, however i got issue in podman run. I have added the docker.io to localhost in /etc/hosts. however i still got this issue, does someone know what i am missing here?
Thank you in advance.
Calling podman run to start the server in container [ibm_mqserver] public port is [51672] ...
Trying to pull docker.io/ibmcom/mq:latest...
Error: initializing source docker://ibmcom/mq:latest: pinging container registry registry-1.docker.io: Get "https://registry-1.docker.io/v2/": dial tcp: lookup registry-1.docker.io on [::1]:53: read udp [::1]:62268->[::1]:53: read: connection refused
below is the error screenshot
Podman Run Error screenshot
As of writing the location for the latest MQ image is icr.io/ibm-messaging/mq:latest
After connecting to VPN I am facing issue with docker-machine create on windows 7. This is the error coming:
This machine has been allocated an IP address, but Docker Machine could not
reach it successfully.
SSH for the machine should still work, but connecting to exposed ports, such as
the Docker daemon port (usually :2376), may not work properly.
You may need to add the route manually, or use another related workaround.
This could be due to a VPN, proxy, or host file configuration issue.
You also might want to clear any VirtualBox host only interfaces you are not using.
Checking connection to Docker...
Error creating machine: Error checking the host: Error checking and/or regenerating the certs: There was an error validating certificates for host "192.168
.99.101:2376": dial tcp 192.168.99.101:2376: connectex: No connection could be made because the target machine actively refused it.
You can attempt to regenerate them using 'docker-machine regenerate-certs [name]'.
Be advised that this will trigger a Docker daemon restart which might stop running containers.
This issue is coming when connecting to vpn. Can anyone please help me with this issue?
Thanks,
Sanjiv
I am trying to connect to mongodb from my system to different system but i am getting following error-

getaddrinfo() resolves domain names through the DNS protocol (which is not related the Netbios Naming System - reason why writing a Windows PC Name is usually a bad idea). Depending of the underlying implementation of the function it might or might not be able to resolve Netbios Names.
Usually using a Netbios computer name is a bad idea, you should rely on a proper DNS architecture.
If you have the exact same error with a mongodb:// URL using solely an IP address, it's weird... Please provide more details on the IP address try case.
Also ensure that the server is not firewalled. Try a netcat connection using netcat for windows:
nc IP 27017 -vv
should say 'Connected'
Netcat for Windows: https://eternallybored.org/misc/netcat/
To be able to connect to mongodb server hosted in another machine, you should be sure that your mongodb server allows connections from addresses other than 127.0.0.1
In the mongod.conf there should be some network interfaces configuration:
# network interfaces
net:
port: 27017
bindIp: 127.0.0.1
To allow any machine to connect to your server the bindIp should be set to: 0.0.0.0
I'm trying to connect to remote docker host through ssh tunnel. I have forwarded the 2375 port and I'm trying to connect to it by specifying DOCKER_HOST.
$ DOCKER_API_VERSION=1.24 DOCKER_HOST=localhost:2375 docker ps
error during connect: Get https://localhost:2375/v1.24/containers/json: http: server gave HTTP response to HTTPS client
This have worked before, but I can't make it work again, because my docker client keep giving me back this error. I can't make it ignore the https/http stuff. The connection is OK, i can curl the endpoints just fine, its just that docker client is doing something and then preventing itself from connecting and I don't know how to make it ignore the https.
I have finally figured out why I was getting this error. I was positive DOCKER_TLS_VERIFY was not set, but it was. So if anyone get this error, make sure the env variable is undefined or that the value is empty.
using
$ DOCKER_API_VERSION=1.24 DOCKER_HOST=localhost:2375 DOCKER_TLS_VERIFY= docker ps
did work as expected.
I am running Docker via CoreOS and Vagrant on OS X 10.10.
When I run docker pull ubuntu in CoreOS, I got following errors:

2014/06/05 12:17:11 Could not find repository on any of the indexed registries.
I'd really appreciate if anyone could give me a useful advise on how to troubleshoot this problem.
Try this temporary workaround:
osx$ boot2docker up
osx$ boot2docker ssh
docker#boot2docker$ sudo echo "nameserver 8.8.8.8" > /etc/resolv.conf
docker#boot2docker$ sudo /etc/init.d/docker restart
It works until reboot.
I don't know about OS X, but on linux this could happen due to "bad" /etc/resolv.conf on the host. For example, ubuntu puts something like:
nameserver 127.0.1.1
and then handles the DNS requests through some service. The problem is, that this is accessible from inside of the image.
To fix this, I had to add some external nameservers, like:
nameserver 127.0.1.1
nameserver 8.8.8.8
nameserver 8.8.4.4
10.0.2.3 is virtualbox dns server, check Fine-tuning the VirtualBox NAT engine
You can as other suggested use 8.8.8.8 which is google dns server.
# /etc/resolve.conf
nameserver 8.8.8.8
And if you work in intranet, then replace it with your normal dns server, which you can add search as well like below
# /etc/resolve.conf
nameserver xxx.xxxx.xxx
search company.com
This will be good to access your private repo
I had a similar issue when trying to pull a container from docker repository with this command :
docker pull ubuntu
Note that I was using coreos inside virtualbox and I was using Nat as my Networking Configuration to have access to internet. When Switching network modes with virtualbox, I couldn't do any pull.
I solved the issue by restarting docker with systemctl by iniating this command :
sudo systemctl restart docker
And then my pull worked fine. I hope this solution helped you. And I got it from from google group issue addressed by one of CoreOS creators(Brandon Philips) through this link:
https://groups.google.com/forum/#!topic/coreos-dev/vWqSbPgNYro
On MacOSX, if you use Docker Machine you can try to:
docker-machine ls
docker-machine ssh YOUR_VM_NAME
and then from within the VM:
kill the /usr/local/bin/docker process and start it again by hand:
sudo /usr/local/bin/docker -d -D -g /var/lib/docker -H unix:// -H tcp://0.0.0.0:2376 --label provider=virtualbox --tlsverify --tlscacert=/var/lib/boot2docker/ca.pem --tlscert=/var/lib/boot2docker/server.pem --tlskey=/var/lib/boot2docker/server-key.pem -s aufs
Funnily enough, restarting like this
sudo /etc/init.d/docker restart
does not help.
On windows I was able to fix it by doing the following:
Go to virtual box application
Delete the VM that was created
Restart computer (optional, i think)
Start Kitematic
Go back to Virtual Box, hit show
Make sure ping google.com command works
Now I am able to download docker images from the hub.
