Hi.. I'm trying to run this docker image.. i'm beginner on this, but, when i try to do the build with "docker build -t node-rfc-docker" i received this message: "docker build" requires exactly 1 argument. See 'docker build --help'.

Usage: docker build [OPTIONS] PATH | URL | - [flags]

Build an image from a Dockerfile

What should i do to run this container to run my nodejs app?

Thanks

Hello,

You must also specify the path which is normally the current dir. So just append a . to the command. 

docker build -t node-rfc-docker .

Should I get any file from this repository and upload in my machine before to execute this command? Thanks.

I have added some steps in the README.md https://github.com/StefanScherer/node-rfc-docker#linux-container You have to download the two files from SAP marketplace.

Stefan sorry for my ignorance, but.. it what's i'm trying to do:

user@instance-1:~$ cd local user@instance-1:~/local$ dir sap user@instance-1:~/local$ cd sap user@instance-1:~/local/sap$ dir nwrfcsdk user@instance-1:~/local/sap$ cd nwrfcsdk user@instance-1:~/local/sap/nwrfcsdk$ dir NWRFC_45-20004565 SAPCAR_721-20010450 user@instance-1:~/local/sap/nwrfcsdk$ docker build -t node-rfc-docker . unable to prepare context: unable to evaluate symlinks in Dockerfile path: lstat /home/user/local/sap/nwrfcsdk/Dockerfile: no such file or directory user@instance-1:~/local/sap/nwrfcsdk$

Ah ok. Well you need to change to the directory with the Dockerfile and create a sub folder download and put the two files SAPCAR_0-80000935.EXE and NWRFC_38-20004565.SAR into that download folder. Then the docker build -t node-rfc-docker . command will work.

The Docker CLI searches for a Dockerfile in current directory so cannot change into another folder.

I see that you have different name for sapcar. You probably have to adjust the Dockerfile to fit your names. SAP sometimes another version with other names.

I think that now i'm beginning to understand.. What files from this repository should i upload to my machine?

StefanScherer commented 6 years ago

You need the Dockerfile, the app.js and package.json files.

If you want to learn more about Docker there are some great online tutorials out there, eg. https://training.play-with-docker.com/beginner-linux/ or https://www.katacoda.com/courses/docker
