Could you please give a brief guide on how to setup the environment without vigrent.

Theoretically - you install docker from here. Then you checkout the repo, you go to the root directory and do docker-compose up. This should easily bring up all the containers. Then one should be able to ssh to them with ssh -i insecure_key root@hostname_of_the_container. @normangilmore - what was the easiest way to ssh to containers?

[normangilmore]

To get into containers, there are two options:

The mildly tedious way is docker ps to get the hex container id, then docker exec -it LONGHEXID bash, but the easy way is docker-compose exec web bash or docker-compose exec spark bash, substituting a container name listed as a services key in docker-compose.yml. The advantage of the first technique is it works from any directory, the second technique requires you to be in or under the directory containing docker-compose.yml.

Note that docker containers are not running sshd as a general rule, so you can't ssh into them. Containers are process wrappers, not virtual machines with a full set of services.

Hope this helps!

[normangilmore]

If and only if you are running Docker Toolbox (which is different than Docker for Mac or Docker for PC!), then you need to first ssh into the VirtualBox VM that docker is running on your behalf.

ssh docker@$(docker-machine ip)
Your ports will be exposed on the internal docker-machine ip, which is usually something like 192.168.99.100.

If you want your ports exposed on localhost, you can do something like this:
ssh -L 80:$(docker-machine ip):80 -L 8080:$(docker-machine ip):8080 docker@$(docker-machine ip), adjusting source and dest ports as needed. You will get a password request, this is for the docker-machine user account on the VM, the password is tcuser. Just leave that window open, and your ports will be tunneled so you can access with http://localhost:8080 or whatever port you mapped to, instead of http://192.168.99.100:8080/

Thanks for your prompt response.

I have tried to run the "docker-compose up" in the root, but unfortunately, I get an error as follows:
D:\code\scrpaybook\scrapybook>docker-compose up

Failed to execute script docker-compose

My install steps are:
1, download the dockertoolbox and install the docker and virtualbox.
2, git clone the scrapybook code to a dir.
3, run "docker-compose up" in above-mentioned dir which have downloaded the code. And then the error .

Thanks!

I just installed DockerToolbox and Virtualbox on Windows 7, and after I ran VirtualBox.exe -msiparams NETWORKTYPE=NDIS5 to downgrade the network driver for Windows 7, I was able to docker-compose up in this repo.

Are you in the Docker Quickstart terminal?

What do you get for python --version?

[normangilmore]

Also, are you able to run docker run hello-world?

[lefeudelavie]

@normangilmore
Thanks for your response. I am able to run "docker run hello-world" on my PC (windows 7 64 bits).
I have installed two python, one is 2.7, another is 3.5.

python --version output as following:
D:\code\scrapybook>python --version
Python 2.7.13

[lefeudelavie]

@normangilmore
And I also have tried to disable path for Python 2.7.13 and change it to Python 3.5, hence I can get Python 3.5 when run 'python --version'. But get the same error when run 'docker-compose up'

[normangilmore]

If you are in the Docker Quickstart Terminal, the proper env variables should be set, as shown in image. But you can set them with the command shown as well.

Enter this command to set them, then try it.
eval $("C:\Program Files\Docker Toolbox\docker-machine.exe" env)

I found the suggestion here, shipping-docker/php-app#19
docs here:
https://docs.docker.com/machine/reference/env/

docker-compose may also want the newer Python I think.

[lefeudelavie]

@normangilmore
I just checked the docker as you mentioned:

But this didn't solve my problem. I think the problem is caused by some other reason. I am trying to reinstall related sw to see if it work.

Hi, I don't want to establish a virtual envirment. And ,what I care about is, how to output the results of the code programms? I only want to see the results in IDLE or Ipython shell or in a file. But I really don't know how to do, what code should I append in the programm.
