I'm having some issue trying to run a CMD command inside a docker container with a Go application.
This is the output I've got:
golang-api | /bin/sh: ./server: not found
golang-api exited with code 127
This is the Dockerfile
FROM golang:1.18-alpine
RUN apk add g++ && apk add make
WORKDIR /app
COPY go.mod go.sum ./
RUN go mod download
COPY . .
RUN make build
EXPOSE 8000
CMD ./server
And this is the Makefile responsible for the build command:
LINUX_AMD64 = GOOS=linux GOARCH=amd64 CGO_ENABLED=1 GO111MODULE=on
migrate:
cd cmd/migrations/$(FOLDER) && go run main.go
build:
cd cmd && $(LINUX_AMD64) go build -a -v -tags musl -o server
And the docker-compose.yml
version: '3.1'
services:
api:
build:
dockerfile: Dockerfile
context: .
container_name: golang-api
ports:
- "8000:8000"
restart: unless-stopped
depends_on:

environment:
- POSTGRES_URL=$POSTGRES_URL
db:
image: postgres
restart: always
environment:
POSTGRES_USER: postgres
POSTGRES_PASSWORD: postgres
ports:

Complete output:

The problem was solved.
Somehow,the RUN cd cmd command seemed not generating the file in the expected directory.
Trying with RUN go build cmd/main.go instead of using the makefile worked, as well pointed by #paltaa in the comments.

I have a project that contains a Dockerfile and a docker-compose.yml.
Dockerfile:
FROM mhart/alpine-node:11 AS builder
WORKDIR /app
COPY . .
RUN yarn install
RUN yarn build
WORKDIR /app
COPY --from=builder /app/build .
CMD ["serve", "-p", "80", "-s", "."]
docker-compose.yml:
version: "3"
services:
front:
build: .
ports:
- 8080:80
restart: always
When I try to run it like below.
docker-compose up -d
I get the following message:

ERROR: Service 'front' failed to build: invalid from flag value builder: pull access denied for builder, repository does not exist or may require 'docker login': denied: requested access to the resource is denied
I saw another question on Stackoverflow, I think it may be close to my problem.
invalid from flag value build: pull access denied for build, repository does not exist or may require 'docker login'
But I only have a build stage, not two stage like in the question from the link.
Your docker build is failing because you are missing a FROM command for your runtime environment. This appears to be a multi-stage docker build, and you are attempting to copy files from a previous build stage named builder but you are still in the first (and only) stage of your build (which is called builder).
You have two options. Either one should work.
Introduce a second runtime stage to your build:
Add another FROM command with the image that you want as your runtime. I just used mhart/alpine-node:11 again here but you may want a different runtime environment.
FROM mhart/alpine-node:11 AS builder
WORKDIR /app
COPY . .
RUN yarn install
RUN yarn build
FROM mhart/alpine-node:11 AS runtime
RUN yarn global add serve
WORKDIR /app
COPY --from=builder /app/build .
CMD ["serve", "-p", "80", "-s", "."]
Make it a non multi-stage build:
Just remove the COPY command and change your workdir to the build directory:
FROM mhart/alpine-node:11 AS builder
RUN yarn global add serve
WORKDIR /app
COPY . .
RUN yarn install
RUN yarn build
WORKDIR /app/build
CMD ["serve", "-p", "80", "-s", "."]

Encountered errors while bringing up the project.
tried adding command RUN chmod u+x ./entrypoint.sh but
the problem is not gone.
Added the build log for COPY entrypoint.sh entrypoint.sh part.
Your entrypoint.sh file get removed from the container when you mount ./web to /app folder as a volume in docker-compose file. so copy entrypoint to root
COPY entrypoint.sh /entrypoint.sh
RUN chmod u+x /entrypoint.sh
And set entrypoint in docker-compose as
entrypoint: /entrypoint.sh
instead of COPY /web ., just do COPY . /app where you are copying the same structure into /app. as you mentioned, workdir /app you are already in that app folder.
or you can just change the last line, COPY entrypoint.sh .
simple docker example : https://github.com/cerofrais/baiscs/tree/master/basic_docker
First, if you want the script to be the normal entrypoint for the image, I'd move that into the Dockerfile with the following:
ENTRYPOINT ["./entrypoint.sh"]
As for why you'd see a file not found error on a script, several potential reasons:
The first line, e.g. #!/bin/bash, points to a command that does not exist in the image you are using. You need to update your script to use the right shell, or change base images to one that includes your shell.
The script is formatted with Windows linefeeds that include a CR before the LF. That turns /bin/sh into /bin/sh^M (sometimes shown as /bin/sh\r) which doesn't exist in the filesystem. This can be fixed by changing the line feed format in your editor, fixing Git to change how linefeeds are automatically changed, or using a tool like dos2unix.
If you run an image for a different platform, and have qemu binfmt_misc installed but without the --fix-binary option, it will look for the interpreter for your platform inside the image rather that from the host. Often this can be fixed with a newer version of binfmt_misc.
The exec format error mentioned in the comments indicates you are running an image designed for another platform on your host. Docker will attempt to pull the proper platform if you have a multi-platform image. However if the image is only built for one platform, and you try to run it on a different platform without something like qemu's binfmt_misc properly configured, you'll get errors. And the fix for that is to change base images to one that supports that CPU architecture and binary format where you are running the image.
This is how I customized Ravisha Hesh's answer and it worked for me.
COPY entrypoint.sh /entrypoint.sh
RUN chmod u+x /entrypoint.sh
CMD ["/entrypoint.sh"]
I am getting error when trying to create /app directory using the files below. This has worked for me in the past so I am not sure what is going wrong now:

I have a set of docker containers that are generated from yml files and work ok.
I now want to deploy them to another machine. In another post here I was advised to build the container on the remote host using one of 2 options:
option1 - copy the code to the remote host and apply a modified docker-compose, and build from source using a modified docker-compose
option2 - create an image on local machine, push it to a docker repository, pull it from there, using a modified docker-compose
I'm trying to follow option1 (as a start). I copied the code into the remote host, and modified the Dockerfile, and docker-compose.yml files (snippet1)
The build goes partway through. It downloads the python and postgres images, and starts to process the Dockerfile, but it fails to install the requirements (it fails to install the first requirement - see snippet2)
What can be the problem?
snippet1 - Dockerfile.dair, and docker-compose.yml

I don't even know where to start with debugging this. When I tried to access the directory it gave me permission error. So I tried to run the command with sudo which didn't help. Any thoughts ?
Little late to reply, but second COPY command COPY . /usr/src/app replaces the /usr/src/app content generated by RUN pip3 install -r requirements.txt.
Try
FROM python:3.6.7-alpine
WORKDIR /usr/src/app
# install in temp directory
RUN mkdir /dependencies
COPY ./requirements.txt /dependencies/requirements.txt
RUN cd /dependencies && pip3 install -r requirements.txt
COPY . /usr/src/app
# copy generated dependencies
RUN cp -r /dependencies/* /usr/src/app/
CMD python3 manage.py run -h 0.0.0.0
As larsks suggests in his comment, you need the file in the services/users directory. To understand why, an understanding of the "context" is useful.
Docker does not build on the client, it does not see your current directory, or other files on your filesystem. Instead, the last argument to the build command is passed as the build context. With docker-compose, this context defaults to the current directory, which you will often see as . in a docker build command, but you can override that as you've done here with ./services/users as your context. When you run a build, the very first step is to send that build context from the docker client to the server. Even when the client and server are on the same host (a common default, especially for desktop environments), this same process happens. Files listed in .dockerignore, and files in parent directories to the build context are not sent to the docker server.
When you run a COPY or ADD command, the first argument (or all but the last argument when you have multiple) refer to files from the build context, and the last argument is the destination file or directory inside the image.
Therefore, when you put together this compose file entry:
build:
context: ./services/users
dockerfile: Dockerfile-dev
with this COPY command:
COPY ./requirements.txt /usr/src/app/requirements.txt
the COPY will try to copy the requirements.txt file from the build context generated from ./services/users, meaning ./services/users/requirements.txt needs to exist, and not be excluded by a .dockerignore file in ./services/users.
I had a similar problem building an image with beryllium, and I solved this deleting it into the .dockerignore
