Docker deployment errors

[tomshomelab]

Building the image with;
docker build -t redditsave .

gives error; "unable to prepare context: unable to evaluate symlinks in Dockerfile path: lstat /home/administrator/Dockerfile: no such file or directory" if i create a file without an extension called "dockerfile" i can get the image to pull but then i get an error;

Step 6/11 : COPY requirements.txt /opt/app/requirements.txt
COPY failed: file not found in build context or excluded by .dockerignore: stat requirements.txt: file does not exist 

if i make the file and continue to do the install i get further errors

the docker compose file in portainer doesnt work either with the error;

failed to deploy a stack: reddit-save Pulling reddit-save Warning failed to solve: rpc error: code = Unknown desc = failed to solve with frontend dockerfile.v0: failed to read dockerfile: open /var/lib/docker/tmp/buildkit-mount333946681/Dockerfile: no such file or directory

im confused, is the docker area a seperate set of instructions, do i need to do the other install steps?

What directory are you in when you run docker build -t redditsave .? You should be in the reddit-save directory, with Dockerfile and requirements.txt there already.
