Usually the credentials needn’t be too obscure, but of course you can change them if you need to – or use another way (beyond the scope of this intro) to specify the details without mentioning them in the Dockerfile.Īt the top of the Dockerfile, in the comments, are the three commands you’ll need to execute to build and run this Docker container.
#Clion installation password#
RUN useradd -m user & yes password | passwd user The Dockerfile then sets up SSH, so CLion can connect into it, and creates a user for CLion to use. You may also be able to get (or create yourself) a base image with all the dependencies already set up. The point is it is just using the base image OS’s package manager (within Docker’s RUN command). Of course if you change the base image you may need to use a different approach to getting dependencies there. Mostly you’ll change the apt-get part, which should be immediately familiar if you’ve used Ubuntu, before.
#Clion installation how to#
It should be fairly obvious how to change this to meet your needs. We’ve created a reference Dockerfile for you to get started. It’s worth going through the introductory docs if you want to get more of a feel for it. We won’t go into this in any more depth, here. That’s one of the things that makes Docker such a fast and productive environment once you get used to it. Each layer is immutable, once created – so any mutations on the layer above can be easily, and cheaply, rolled back – without having to recreate all the layers beneath. Secondly, each line in a Dockerfile is executed on what Docker calls a layer. We’ll use a Ubuntu base image to give us a common platform to start with – but other OS images are available. These look like simple scripts, but have a few special properties that make them a bit special.įirst, you can refer to a “base image”, which is a prebuilt container, usually available via a docker registry, which does a lot of the heavy lifting. Creating a Docker container for use with CLion.ĭocker containers are described in Dockerfiles. The docs are excellent throughout, and the installation instructions are no exception – so check them out for your platform. This is fairly straightforward, although there may be a few extra steps, depending on your platform.
#Clion installation install#
If you don’t already have it you’ll need to install the Docker Engine. It sounds complex to set-up, but one of the surprises for many is just how easy it is to get going.
