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.

  • Your containers don't appear to have access to the Internet. – Michael Hampton Dec 28 '15 at 12:01

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).

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 .

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

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.
