Since version 2.2.0.0, docker for macOS allows users to access the host’s SSH agent inside containers. Here’s an example command that let’s you do it: docker run –rm -it \ -v /run/host-services/ssh-auth.sock:/ssh-agent \ -e SSH_AUTH_SOCK=”/ssh-agent” \ my_image Note that you have to mount the specific path (/run/host-services/ssh-auth.sock) instead of the path contained in $SSH_AUTH_SOCK environment … Read more
The uname command is pulling specs from the kernel running on the host. If I enter a Ubuntu container on my Debian host, the uname will answer with a Debian build of the kernel. To know the version of Ubuntu you are running, do a $ cat /etc/lsb-release DISTRIB_ID=Ubuntu DISTRIB_RELEASE=16.04 DISTRIB_CODENAME=xenial DISTRIB_DESCRIPTION=”Ubuntu 16.04.3 LTS” It’s … Read more
Inside boot2docker (boot2docker ssh) / docker-machine (docker-machine ssh default) , open or create the file /var/lib/boot2docker/profile and add the following line: EXTRA_ARGS=”–dns 192.168.1.145″ Also works for: EXTRA_ARGS=”–insecure-registry myinternaldocker” After the change you need to restart the docker daemon: sudo /etc/init.d/docker restart Or leave boot2docker / docker-machine and restart the entire virtual machine: boot2docker restart # … Read more
In your backend app, connect to mongodb:27017 instead of 127.0.0.1:27017. Where ‘mongodb’ is the name of your service within docker-compose.yml.
Thanks to palimpestor’s answer I figured it out: Instead of –net=”host”, use –add-host=”localhost:10.0.2.2″ Indeed: 10.0.2.2 is the default gateway defined for the guest network interface in NAT mode (reference). Read: it’s your host, seen from boot2docker. –add-host… is adding localhost 10.0.2.2 in /etc/hosts (reference) Note: you need to have set up a NAT adapter in … Read more
This general issue has been plaguing me for a couple of months. I first noticed it when trying to get a local virtual machine to fetch Python packages, so I already had an idea that certificates would be an issue. I solved it for my VMs, but hadn’t until today been able to work out … Read more
Not sure if it helps under windows. But for Mac see: boot2docker together with VirtualBox Guest Additions How to mount /Users into boot2docker https://medium.com/boot2docker-lightweight-linux-for-docker/boot2docker-together-with-virtualbox-guest-additions-da1e3ab2465c tl;dr Build your own custom boot2docker.iso with VirtualBox Guest Additions (see link) or download http://static.dockerfiles.io/boot2docker-v1.0.1-virtualbox-guest-additions-v4.3.12.iso and save it to ~/.boot2docker/boot2docker.iso.
This is an improvement of the selected answer because that answer is limited to c:\Users folder. If you want to create a volume using a directory outside of c:\Users this is an extension. In windows 7, I used docker toolbox. It used Virtual Box. Open virtual box Select the machine (in my case default). Right … Read more
The config files you need to modify won’t be on your OS X file system, they’ll be attached to the Tiny Core Linux VM which acts as your local Docker server. To configure the proxy for that, first start Boot2docker from Applications. Once it’s started, get a terminal window and ssh into the VM: bash-3.2$ … Read more
The answer is actually the first comment. I’ll explain Miguel’s comment a bit. First, we need to understand that a Docker container runs a single command. The container will be running as long as that process the command started is running. Once the process is completed and exits then the container will stop. With that … Read more
