Now, letвЂ™s create a file name Dockerfile. Then we will create the python script which we will run, letвЂ™s name it main.py and write the following code into that. First, we will create a folder containing all the necessary things such as python file, docker image etc.

#Ubuntu python 3.6 docker container install#

We have to install the dependency inside our docker container. So, in this program, we have a dependency, and that is NumPy. Here we will create a simple script that will measure the square root of a number using the pythonвЂ™s NumPy library. Now, itвЂ™s time to create our first program that will run on docker. This will download a test container and print some messages and then it will exit. Then run the following command to test the docker system. We can do this by using the following commands: $ sudo groupadd dockerДЄfter running this command, you have to logout or restart the pc. Now, the docker should be installed in our system, but before we test it, first we need to add the docker into usergroup, otherwise in some system it will give error.

$ sudo apt-get install docker-ce docker-ce-cli containerd.io

#Ubuntu python 3.6 docker container update#

To install the docker engine first we have to update the apt package again and run the following commands: $ sudo apt-get update

We will use the following command to set up the stable repository. Now we need to add the DockerвЂ™s official GPG key to the system. Then we need to update the apt packages and install the following dependencies by running the commands: $ sudo apt-get update We will run the following command in the terminal to do that: $ sudo apt-get remove docker docker-engine docker.io containerd runc First of all, we are going to uninstall previously installed docker (if have any).

Still, it is faster than the virtual machine. Docker will allow you to create a virtual machine to install all your dependencies for your specific project without tempering your primary system. I had to reinstall new libraries, which is doing a new thing repeatedly, and itвЂ™s time-consuming. I always get in trouble when creating a new project with different dependencies installed on my machine.
