The make docker target spits out some SyntaxError. With this .dockerignore there is no more error. Explanation: - the python files are compiled while building the docker image - a node modules contains some python files - the python files inside the node module doesn't compile It raises the fact that node_modules were included in the docker image which should not happen. Same the local directory was included. Dockerfile builds searx in its own way (without virtualenv) Thanks @dalf: - https://github.com/asciimoo/searx/pull/1900#issuecomment-604892737 Signed-off-by: Markus Heiser <markus.heiser@darmarit.de>
