I use a windows laptop
This is the error
ERROR: for web Cannot start service web: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: exec: "flask": executable file not found in $PATH: unknown

ENTRYPOINT ["/usr/src/app/entrypoint.sh"]
Building the image works fine, but when I try a docker run after building the image I get the following error:
docker: Error response from daemon: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: exec: "/usr/src/app/entrypoint.sh": permission denied: unknown.
ERRO[0000] error waiting for container: context canceled
The line RUN chmod +x /usr/src/app/entrypoint.sh doesn't seem to work because when I comment the ENTRYPOINT statement, build the image then start a containerI can see that the execution right isn't added for that file.
Docker version is:
Docker version 20.10.23, build 7155243
I tried replacing the RUN chmod line with a --chmod=777 option to the COPY of the entrypoint and it didn't change anything.
Any idea why a chmod +x would fail in docker ?
I found a workaround by removing the chmod line and replacing the entrypoint line with the following:
ENTRYPOINT ["/bin/sh", "/usr/src/app/entrypoint.sh"]
This way there is no need for a execution right on the entrypoint script.
But I still don't know why the chmod doesn't work.
Here's my dockerfile:
FROM tiangolo/uvicorn-gunicorn-fastapi:python3.7
COPY ./app /app/app
WORKDIR /app/app
RUN "pip install -r requirements.txt"
And here's my folder structure:
When I try to build the image using docker build -t myimage ., I get the following error:
Any insight into resolving this would be appreciated.
Try
RUN ["pip", "install", "-r", "requirements.txt"]

Creating maps_web_1 ... error
ERROR: for maps_web_1 Cannot start service web: OCI runtime create failed: container_linux.go:349: starting container process caused "exec: \"./entrypoint2.sh\": stat ./entrypoint2.sh: no such file or directory": unknown
How do I tell Docker how to reference that entrypoint file? The docker-compose.yml file section including the above is below
web:
restart: always
build: ./web
ports: # to access the container from outside
- "8000:8000"
env_file: .env
environment:
DEBUG: 'true'
command: /usr/local/bin/gunicorn directory.wsgi:application --reload -w 2 -b :8000
volumes:
- ./web/:/app
depends_on:
- mysql
Based on the provided Dockerfile and docker-compose file you are doing the following
Copy files (entrypoint + requirments) to /app
Install the needed packages
Start containers with the volume that overwrite the content of the /app, which is causing the issue.
To solve the issue you have to do one of the following
Copy all the data from ./web to the docker image and remove the volume
Dockerfile : add the following lines
WORKDIR /app/
COPY ./web /app
Docker-compose: remove the below lines
volumes:
- ./web/:/app
The second option is to change the path of the entry point so it does not conflict with the volume
Dockerfile
RUN tr -d '\r' < entrypoint.sh > /entrypoint2.sh
RUN chmod +x /entrypoint2.sh
ENTRYPOINT ["./entrypoint2.sh"]
I am trying to install tesseract-ocr to use within a docker container, but when I feed a request to my api, I still get an error saying "FileNotFoundError: [Errno 2] No such file or directory: 'tesseract': 'tesseract'"
I'm trying to maybe add tesseract to my ENV $Path variable in the Dockerfile, but I'm unable to locate where this tesseract package is even installed. Below I've added my Dockerfile, any help would be appreciated. Thanks!

When I was trying to build golang using docker
The image build of docker was successful, but the following error occurred when running with docker run
docker: Error response from daemon: OCI runtime create failed: container_linux.go:345: starting container process caused "exec: \"/app\": permission denied": unknown.
I think this error cause no user add, so I added group and user as below
RUN groupadd -g 10001 myapp \
&& useradd -u 10001 -g myapp myapp
but didn't fix.
Here is my source docker file
FROM golang:1.12.9 as builder
ADD . /go/src/appname/
WORKDIR /go/src/appname/
ENV GO111MODULE=on
COPY go.mod .
COPY go.sum .
RUN go mod download
COPY . .
RUN CGO_ENABLED=0 GOOS=linux GOARCH=amd64 make build target=prod
FROM alpine
RUN apk update \
&& apk add --no-cache
COPY --from=builder /go/src/ /app
ENTRYPOINT [ "/app" ]
thanks
You are copying your entire source folder into the directory /app in this step:
COPY --from=builder /go/src/ /app
Then you try to execute the directory:
ENTRYPOINT [ "/app" ]
Instead, you need to copy the compiled binary that your go build outputs in the copy step.
You need to specify the output directory to your binary.
RUN CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build -a -o /app .
then copy the app directory
COPY --from=builder /app ./
RUN chmod +x ./app
ENTRYPOINT ["./app"]
Thanks to the advice of everyone, I fix this issue
I couldn't just COPY with the build binary properly specified
before
COPY --from=builder /go/src/ /app
after
COPY --from=builder /go/src/build/build_app_name /app
thanks!!
