Using Docker volumes and setting the appropriate -dbpath when running mongod would prevent this from happening.įinally, instead of running a bunch of shell scripts, you may find it more convenient to automate this whole process by using multi-container automation tools like docker-compose. In case we remove one of our containers by mistake, the data would also vanish.Run at least one container on a different server and access it through its external ip address and port (in our case the external facing ports for out containers were 30001, 30002, and 30003 for mongo1, mongo2, and mongo3 respectively). Keeping all containers on a single server is not the best idea.Be sure to add users and passwords when deploying this solution on an actual server. None of the databases have any administrative security measures.Although this set up is great to experiment and play around with replica sets, there are some precautions to be taken before moving it to production : Going forwardĪs you can see, with the power of docker we were able to get a mongo replica set up and running in ~5 minutes. We run the db2.setSlaveOk() command to let the shell know that we re intentionally querying a database that is not our primary.Īnd it looks like the same document is present in our secondary as well. To learn the IP address, run multipass list. And, you should be able to run this: ssh -l ubuntu 192.168.64.21 docker run hello-world. Click on open, you will get a prompt asking if you trust the key, if this is the first time you have used SSH, just press OK or accept. You may also use grep command to get just the lines matching the string 'IPAddress'. Once those steps are accomplished you should be able to run ssh -l ubuntu IP-ADDRESS to get a shell prompt inside the Ubuntu instance. Hi, I've installed docker on Oracle Linux 6.7 UEKR4 but I can't start a container on a specific ip address, according to the log change for docker 1.1. Open up Putty, the only thing you need to enter is the IP address of your NAS and select the SSH radio button.
sc config docker binpath '\'C:\Program Files\docker\dockerd.exe\' -run-service -H tcp://0.0.0.0:2375'. Run the following command in a command prompt (cmd.exe not PowerShell): cmd. Using this method, Docker Engine flags are set directly on the Docker service.
Go towards the end and look into the Networks section to get the container's IP address. The Docker Engine can also be configured by modifying the Docker service with sc config. db2 = ( new Mongo ( 'mongo2:27017' ) ). The inspect command gives you many details about the container you are inspecting.
