Pip Install Inside Docker

Pip install Faker. And let’s create a file called process.py in the package folder. Installing your private package from inside a Docker container.

If you’re building production ML systems, dev containers are the killer feature of VS Code. Dev containers give you full VS Code functionality inside a Docker container. This lets you unify your dev and production environments if production is a Docker container. Pip install geopandas && pip install nnabla && pip install vowpalwabbit && # papermill can replace nbconvert for executing notebooks: pip install cloud-tpu-client && # b/188429515#comment7 tensorflow-cloud = 0.1.14 installs tensorflow-transform which install apache-beam which downgrades the google.cloud library to 1.x. The DeepLabCut version in this container is equivalent to the one you install with pip install 'deeplabcutgui'. If you not need the GUI, you can run the light version of DeepLabCut and open a terminal by running $ deeplabcut-docker bash Inside the terminal, you can confirm that DeepLabCut is correctly installed by running.

Question or problem about Python programming:

I’m following the fig guide to using docker with a python application, but when docker gets up to the command

Install

I get the following error message:

This repeats several times and then I get another message:

So for some reason pip can’t access any packages from inside a docker container. Is there anything I need to do to allow it internet access?

However pip works fine to install things outside of the docker container, and worked fine even with that exact package (blinker1.3) so that’s not the problem. Also this problem isn’t specific to that package. I get the same issue with any pip install command for any package.

Does anyone have any idea what’s going on here?

How to solve the problem:

Solution 1:

Your problem comes from the fact that Docker is not using the proper DNS server.
You can fix it in three different ways :

1. Adding Google DNS to your local config

Modifying /etc/resolv.conf and adding the following lines at the end

# Google IPv4 nameservers
nameserver 8.8.8.8
nameserver 8.8.4.4

If you want to add other DNS servers, have a look here.

However this change won’t be permanent (see this thread). To make it permanent :
$ sudo nano /etc/dhcp/dhclient.conf

Uncomment and edit the line with prepend domain-name-server :
prepend domain-name-servers 8.8.8.8, 8.8.4.4;

Restart dhclient : $ sudo dhclient.

2. Modifying Docker config

As explained in the docs :


Systems that run Ubuntu or an Ubuntu derivative on the desktop typically use 127.0.0.1 as the default nameserver in /etc/resolv.conf file.
To specify a DNS server for use by Docker :

3. Using a parameter when you run Docker

When you run docker, simply add the following parameter : --dns 8.8.8.8

Solution 2:

I needed to add –network=host to my docker build command:

Solution 3:

I had the same issue and it plagued me for a while and I tried a lot of solutions online but to no avail. However I finally resolved it as follows:

Install Pip In Docker Centos

Running:
  1. Discover the address of your DNS server.

    Discover the address of your DNS server by running the following command:

  2. Update the Docker daemon

    Create a docker config file at /etc/docker/daemon.json. (if you don’t already have one) and add the following content to the file:

    The first item of the array is your network’s DNS server and the second is google’s DNS server as a fallback when if your network’s DNS is not available.

    Save the file and then restart the docker service

Solution 4:


ok, restarting my docker-machine is solving the problem. thanks – ismailsunni

This was the solution for me:

Packages

Solution 5:

For me simply restarting docker daemon helped.

Solution 6:

For Ubuntu users

You need to add new DNS addresses in the docker config

Add the dns after ExecStar.

Should look like that:

Then do:

Should work.

Pip Install Inside Docker Linux

In my case, with docker version 1.13.0 and docker-machine 0.9.0 under Ubuntu 16.04 I had to modify slightly Tanzaho’s answer (2. Modifying Docker config) as follows:

  1. Log into Ubuntu as a user with sudo privileges.

  2. Open the /etc/default/docker file for editing:

  3. Add the following setting for Docker.

  4. Save and close the file.

  5. Restart the Docker daemon :

Solution 8:

For me, I was unable to install pip due to the docker’s DNS not configured properly. I’ve tried the above steps, however, configuring docker DNS to Google DNS does not work for my laptop. Docker’s DNS can be properly configured only if I set its DNS to my laptop’s assigned IP.

If you use Ubuntu, you can use the following steps to configure your docker’s DNS:

  1. Find out your device’s assigned IP. You can find this by either

    • Checking the inet addr of your ethernet or wlan in ifconfig
    • Choosing any address in nmcli dev show grep 'DNS'
  2. Edit dns in /etc/docker/daemon.json (create this file if it doesn’t exist previously)

  3. Restart docker: sudo service docker restart

Solution 9:

In case someone is reading this using docker-compose. I managed to resolve this by changing my yaml file as follows

which is equivalent to writing

Pip Install Inside Docker

As a Docker newbie, I had a problem that manifested itself in this way when I was following the tutorial for Docker at:

I’m using Docker 17.03.1-ce on a corporate LAN.

I checked and double checked my DNS settings. I’d used various ways of configuring the DNS that I’d found in my searches across the Internet. Some caused errors on startup. The approach that I ultimately settled upon for configuring the DNS was the one in the Troubleshoot Linux section of the above link above where the DNS is configured via the daemon.json file in the /etc/docker directory.

Pip Install Inside Dockerfile

Docker

However, I still had this same issue. What finally solved the problem for me was the configuration of the proxy via the http_proxy and https_proxy environment variables. I had them specified in my Dockerfile, but I neglected to do so before the RUN pip command.

Even though it appeared to be a DNS issue, moving these ENV commands ahead of the RUN command made the difference for me. In case that is helpful for anyone with this problem.
