I am new about docker, so ,if any wrong thoughts come from me ,please point out it.Thanks~
I aim at running a web server that was developed by me ,or a team I belong to,in the docker.
So, I thought out three steps:
Have a image ,copy the web files into it,and run the container.so,I do the step below:
1- get a docker image.
I try like this : docker pull centos, so that I can get a image based on centos.Here, I did not care about the version of centos,of course, it's version is 6.7 or ,just taged:latest.
Here,I check the image by docker images,and I can see it like this:
REPOSITORY TAG IMAGE ID CREATED SIZE
docker.io/centos latest d123f4e55e12 3 weeks ago 196.6 MB
So,I think this step successed.
2- try copying the files in local system to the container.
I stop at the path: /tornado,which had a folder named fordocker .The
fordocker contains the web-server files.
I try commonds like this(based on the guide):
docker cp fordocker/ d123f4e55e12:/web
But! Here comes the error:
Error response from daemon: No such container: d123f4e55e12
3- if I copy the files successfully,I could try like this:docker run -d centos xxx python web.py.
This step will come error?I don't know yet.
I searched a lot ,but do not explain the phenomenon.
It seemed that everyone,beside me ,use the commond would succes.
So,here comes the questions:
1- Is the method I thought out feasible? Must I create a images through profile?
2- Where comes the error if the method is feasible? Did the commond cp based on otherthings that I had not done?
3- What should I do if the method is not feasible?Create a image myself?
Have a good day~
