Out-of-the-box Debian docker image with SSH access
4+
Simple Debian docker images with SSH access
5+
6+
7+
Usage
8+
-----
9+
10+
To create the image `tutum/debian` with one tag per Debian release,
11+
execute the following commands on the tutum-debian folder:
12+
13+
docker build -t tutum/debian:squeeze squeeze/
14+
docker build -t tutum/debian:wheezy wheezy/
15+
16+
To create different images for every Debian release, with just one `latest` tag each,
17+
execute the following commands on the tutum-debian folder:
18+
19+
docker build -t tutum/debian-squeeze squeeze/
20+
docker build -t tutum/debian-wheezy wheezy/
21+
22+
23+
Running tutum/debian
24+
--------------------
25+
26+
To run a container from the image you created earlier with the `wheezy` tag
27+
binding it to port 2222 in all interfaces, execute:
28+
29+
docker run -d -p 2222:22 tutum/debian:wheezy
30+
31+
The first time that you run your container, a random password will be generated
32+
for user `root`. To get the password, check the logs of the container by running:
33+
34+
docker logs <CONTAINER_ID>
35+
36+
You will see an output like the following:
37+
38+
========================================================================
39+
You can now connect to this Debian container via SSH using:
40+
41+
ssh -p <port> root@<host>
42+
and enter the root password 'U0iSGVUCr7W3' when prompted
43+
44+
Please remember to change the above password as soon as possible!
45+
========================================================================
46+
47+
In this case, `U0iSGVUCr7W3` is the password allocated to the `root` user.
48+
49+
Done!
50+
51+
52+
Setting a specific password for the root account
53+
------------------------------------------------
54+
55+
If you want to use a preset password instead of a random generated one, you can
56+
set the environment variable `ROOT_PASS` to your specific password when running the container:
57+
58+
docker run -d -p 2222:22 -e ROOT_PASS="mypass" tutum/debian:wheezy
59+
