Using DockerToolbox, I've been trying for the past few days to update my container to run in heroku.
I cant seem to update the code in the container.
Here are some of things I've tried:
in Docker file change COPY . /app to ADD . /app
Removed docker machine and create a virtualbox
`docker-machine rm default`
`docker-machine create --drive virtualbox default`
build/run docker image
`docker build --no-cache -t appname`
`docker run -it -p 8888:8080 appname`
Also tried docker build --no-cache .
Docker File
FROM python:3.6
# create and set working directory
RUN mkdir /app
WORKDIR /app
# Add current directory code to working directory
ADD . /app/
# set default environment variables

This looks like a common issue so I checked a few SO posts but none of them solved my problem.
Here is my Dockerfile:
# MkDocs container
FROM python:3-alpine AS build-env
RUN apk add bash
RUN pip install --upgrade pip
RUN pip install pymdown-extensions \
&& pip install mkdocs \
&& pip install mkdocs-material \
&& pip install mkdocs-rtd-dropdown \
&& pip install mkdocs-git-revision-date-plugin \
&& pip install mkdocs-git-revision-date-localized-plugin \
&& pip install mkdocs-redirects
# executed at ~/Developer/MkDocs
RUN mkdir -p /home/mkdocs/
WORKDIR /home/mkdocs/
COPY . .
RUN mkdocs build -s
WORKDIR /
# Nginx container
FROM nginx:1.21.6-alpine
RUN apk add bash
EXPOSE 80
RUN cat /etc/nginx/nginx.conf
COPY nginx.conf /etc/nginx/nginx.conf
WORKDIR /
RUN mkdir -p /home/mkdocs
COPY --from=build-env /home/mkdocs/site/ /home/mkdocs/
RUN mv /home/mkdocs/* /usr/share/nginx/html/
RUN chown nginx:nginx /usr/share/nginx/html/*
USER nginx:nginx
And here is the command to run docker:
docker run -it --name mkdocs -p 8789:80 nginx
Running localhost:8789 only shows the default nginx homepage, not the built one of MkDocs. I also run docker exec -it --user root <PID> bash to check the directory /usr/share/nginx/html/ but the copied files are not there.
My other checks:
First, I'm 100% sure that the files built in the first stage works and exists
Second, this is what completely frustrated me out. If I run the docker using docker run -it --entrypoint=/bin/bash mkdocs:v1, I can actually see the built MkDocs files:
bash-5.1$ ls /usr/share/nginx/html
404.html 50x.html assets index.html search sitemap.xml sitemap.xml.gz
bash-5.1$
I have been trying for almost 3 weeks to build and run a meteor app (bundle) using Docker, I have tried all the majors recommendations in Meteor forums, Stackoverflow and official documentarion with no success, first I tried to make the bundle and put inside the docker but have awful results, then I realized what I need to do is to make the bundle inside the docker and use a multistage Dockerfile, here is the one I am using right now:
FROM chneau/meteor:alpine as meteor
USER 0
RUN mkdir -p /build /app
RUN chown 1000 -R /build /app
WORKDIR /app
COPY --chown=1000:1000 ./app .
COPY --chown=1000:1000 ./app/packages.json ./packages/
RUN rm -rf node_modules/*
RUN rm -rf .meteor/local/*

RUN meteor update --packages-only
RUN meteor npm ci
RUN meteor build --architecture=os.linux.x86_64 --directory /build

RUN mkdir -p /app
RUN chown 1000 -R /app

ENV MONGO_URL=mongodb://locahost:21027/meteor
ENV PORT=3000
EXPOSE 3000
ENTRYPOINT [ "/usr/local/bin/node", "/app/main.js" ]
if I build with docker build -t my-image:v1 . then run my app with docker run -d --env-file .dockerenv --publish 0.0.0.0:3000:3000 --name my-bundle my-image:v1 it exposes port:3000 but when I try to navigate with my browser to http://127.0.0.1:3000 it redirects to https://localhost, if i do docker exec -u 0 -it my-bundle sh, then apk add curl, then curl 127.0.0.1:3000 I can see the meteor app running inside docker.
Has anyone had this issue before, maybe I am missing some configuration? my bundle also works fine outside docker with node main.js in the bundle folder and can visit http://127.0.0.1:3000 with my browser.
Thanks in advance
I am new to docker and trying to learn it by it's documentation. AS i need to create a NextJS build using docker image for nginx server i have followed the below process.
Install the nginx
Seeding the port 80 to 3000 in the default config.
Symlink the out directory to base nginx directory
CMD to take care the production build and symlinking of the out directory.
FROM node:alpine AS deps
RUN apk add --no-cache libc6-compat git
RUN apt-get install nginx -y
WORKDIR /sample-app
COPY package.json yarn.lock ./
RUN yarn install --frozen-lockfile
FROM node:alpine AS builder
WORKDIR /sample-app
COPY . .
COPY --from=deps /sample-app/node_modules ./node_modules
RUN yarn build
FROM node:alpine AS runner
WORKDIR /sample-app
ENV NODE_ENV production
RUN ls -SF /sample-app/out /usr/share/nginx/html
RUN -p 3000:80 -v /sample-app/out:/usr/share/nginx/html:ro -d nginx
RUN addgroup -g 1001 -S nodejs
RUN adduser -S nextjs -u 1001
RUN chown -R nextjs:nodejs /sample-app/out
USER nextjs
CMD ["nginx -g daemon=off"]
While running the docker build shell script command as sudo docker build . -t sample-app it throws the error The command '/bin/sh -c apt-get install nginx -y' returned a non-zero code: 127
I do not have much experience with alpine images, but I think that you have to use apk (Alpine Package Keeper) for installing packages
try apk add nginx instead of apt-get install nginx -y
I am basing my dockerfile on the rust base image.
When deploying my image to an azure container, I receive this log:
./bot: /lib/x86_64-linux-gnu/libm.so.6: version `GLIBC_2.29' not found (required by ./bot)
./bot is my application.
The error also occurs when I perform docker run on my Linux Mint desktop.
How can I get GLIBC into my container?
Dockerfile
FROM rust:1.50
WORKDIR /usr/vectorizer/
COPY ./Cargo.toml /usr/vectorizer/Cargo.toml
COPY ./target/release/trampoline /usr/vectorizer/trampoline
COPY ./target/release/bot /usr/vectorizer/bot
COPY ./target/release/template.svg /usr/vectorizer/template.svg
RUN apt-get update && \
apt-get dist-upgrade -y && \
apt-get install -y musl-tools && \

CMD ["./trampoline"]
Now I don't totally understand the dependencies of your particular project but the below Dockerfile should get you started.
What you want to do is compile in an image that has all of your dev dependencies and then move the build artifacts to a much smaller (but compatible) image.
FROM rust:1.50 as builder
RUN USER=root
RUN mkdir bot
WORKDIR /bot
ADD . ./
RUN cargo clean && \
cargo build -vv --release
FROM debian:buster-slim
ARG APP=/usr/src/app
ENV APP_USER=appuser
RUN groupadd $APP_USER \
&& useradd -g $APP_USER $APP_USER \
&& mkdir -p ${APP}
# Copy the compiled binaries into the new container.
COPY --from=builder /bot/target/release/bot ${APP}/bot
RUN chown -R $APP_USER:$APP_USER ${APP}
USER $APP_USER
WORKDIR ${APP}
CMD ["./trampoline"]
Hi I have a docker file which is failing on the COPY command. It was running fine initially but then it suddenly crashed during the build process. The Docker file basically sets up the dev environment and authenticate with GCP.

Any leads in this would be helpful.
How are you running docker build command?
In docker best practices I've read that docker fails if you try to build your image from stdin using -
Attempting to build a Dockerfile that uses COPY or ADD will fail if this syntax is used. The following example illustrates this:
# create a directory to work in
mkdir example
cd example
# create an example file
touch somefile.txt
docker build -t myimage:latest -<<EOF
FROM busybox
COPY somefile.txt .
RUN cat /somefile.txt
EOF
# observe that the build fails
...
Step 2/3 : COPY somefile.txt .
COPY failed: stat /var/lib/docker/tmp/docker-builder249218248/somefile.txt: no such file or directory
I've reproduced issue... Here is my Dockerfile:
FROM alpine:3.7
## ENV Variables
ENV PYTHON_VERSION="3.6.5"
ENV BUCKET_NAME='detection-sandbox'
ENV DIRECTORY='/usr/local/gcloud'
# working directory
WORKDIR /usr/src/app
COPY kk.txt ./ \
kk.2.txt ./
If I create image by running docker build -t testImage:1 [DOCKERFILE_FOLDER], docker creates image and works correctly.
However if I try the same command from stdin as:
docker build -t test:2 - <<EOF
FROM alpine:3.7
ENV PYTHON_VERSION="3.6.5"
ENV BUCKET_NAME='detection-sandbox'
ENV DIRECTORY='/usr/local/gcloud'
WORKDIR /usr/src/app
COPY kk.txt ./ kk.2.txt ./
EOF
I get the following error:
Step 1/6 : FROM alpine:3.7

It seems that docker build images from /var/lib/docker/tmp/ if you build image from stdin, thus ADD or COPY commands don't work.
Incorrect path in source is a common error.
Use
COPY ./directory/testproject-264512-9de8b1b35153.json /dir/
instead of
COPY testproject-264512-9de8b1b35153.json /dir/
