Unable to install CURL on Docker Ubuntu image

Question

I'm trying to install curl on ubuntu 14.04 in Docker image and the simple:

sudo apt-get update sudo apt-get install curl

will never work with the following output. It seems that curl installation is impossible through apt-get on this Docker image. I will be thankful for any help as I'm new to running Docker.

Answer 1

It seems like you can't access those resources because the DNS are not configured. Check if you have access to them (ping 8.8.8.8) and then configure the DNS for the docker (adding nameserver 8.8.8.8 to /etc/resolv.conf).

Answer 2

I tried to make a Dockerfile and reproduced the problem. Seems you are lacking dns configuration. Below I try to build a Dockerfile with basic contents (CMD tail) and tag it as trusty.

anovil@ubuntu-anovil:~/tmp/serverfault$ cat Dockerfile FROM ubuntu:trusty RUN apt-get update \ && apt-get install -y curl CMD tail -f /dev/null anovil@ubuntu-anovil:~/tmp/serverfault$ docker build -t trusty . Sending build context to Docker daemon 2.048 kB Step 1 : FROM ubuntu:14.04 14.04: Pulling from library/ubuntu Digest: sha256:d3b59c1d15c3cfb58d9f2eaab8a232f21fc670c67c11f582bc48fb32df17f3b3 Status: Downloaded newer image for ubuntu:14.04 ---> 89d5d8e8bafb Step 2 : RUN apt-get update && apt-get install -y curl ---> Using cache ---> 23e51481a6b8 Successfully built 23e51481a6b8 

Instead of just running it, pass the dns of your choice or global dns like this:

anovil@ubuntu-anovil:~/tmp/serverfault$ docker run -d --dns=8.8.8.8 trusty 5fe788260e6e43157fc06d991f994a6fd029624fb71dc6662024f2c118ac7577 anovil@ubuntu-anovil:~/tmp/serverfault$ docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 5fe788260e6e trusty "/bin/sh -c 'tail -f " 3 seconds ago Up 2 seconds gloomy_dijkstra anovil@ubuntu-anovil:~/tmp/serverfault$ 

Alternatively you could check whats the nameserver your docker container is using like this:

anovil@ubuntu-anovil:~/tmp/serverfault$ docker run -it trusty cat /etc/resolv.conf search xyz.com nameserver A.B.C.D anovil@ubuntu-anovil:~/tmp/serverfault$ docker run -it --dns=8.8.8.8 trusty cat /etc/resolv.conf search xyz.com nameserver 8.8.8.8 anovil@ubuntu-anovil:~/tmp/serverfault$ 

You could clearly see the difference in the resolve.conf inside the container.

Let us know how it went.
