Ways to use existing docker as a test¶
I have my previous easy-prime docker. It is for prime editing. But users come to me a lot for just sgRNA design. I modified my code a little bit and I don’t want to build a docker image from scratch. This is how I test my code and build new image:
# First, create a testing container to test my code, my easy-prime will always use 80, so I have to create a new port. The resulting new link is: http://127.0.0.1:90/
docker container create -p 80:80 -p 90:90 -v /e/Docker/easy_gRNA_design:/app2 --name tmp3 liyc1989/easy_prime
# I can then using docker desktop to open a terminal, go to app2 and test my code.
# remember for your docker file, you need to change its port to 90 for testing
# Then, once the code is finished, we need to create a new container and replace the old files in "app" folder.
docker container create -p 80:80 --name tmp4 liyc1989/easy_prime
# suppose your are in your working dir
docker cp app.py tmp4:/app
docker cp config.yaml tmp4:/app
docker cp utils.py tmp4:/app
# Last, create new image and push to docker hub
docker commit tmp4 easy_ngg_design
docker login
docker tag easy_ngg_design liyc1989/easy_ngg_design
docker push liyc1989/easy_ngg_design
