I need to have a Dockerfile with Python3 and the latest version of OpenCV. The Dockerfile I have written is described below:
FROM ubuntu
#Install OpenCV
RUN apt-get update &&\
apt-get install -y cmake
RUN apt-get install -y gcc g++
RUN apt-get install -y python3-dev python3-numpy
# To support GUI features
RUN apt-get install -y libavcodec-dev libavformat-dev libswscale-dev
# To support GTK 2
RUN apt-get install -y libgtk2.0-dev
# To support GTK 3
RUN apt-get install -y libgtk-3-dev
#Optional dependencies
RUN apt-get install -y libpng-dev
RUN apt-get install -y libjpeg-dev
RUN apt-get install -y libopenexr-dev
RUN apt-get install -y libtiff-dev
RUN apt-get install -y libwebp-dev
# Clone OpenCV repo
RUN apt-get install -y git
RUN git clone https://github.com/opencv/opencv.git
#Compile
RUN mkdir /opencv/build && \
cd /opencv/build
RUN cmake ..
RUN make
However, when i run it, it gives me the following error with cmake.
Step 17/27 : RUN cmake ..
---> Running in 3dca32df2036
CMake Error: The source directory "/" does not appear to contain CMakeLists.txt.
Specify --help for usage, or press the help button on the CMake GUI.
The command '/bin/sh -c cmake ..' returned a non-zero code: 1
Do you know what am i doing wrong?
You just need to chain the last RUN instructions:
#Compile
RUN mkdir /opencv/build && \
cd /opencv/build && \
cmake .. && \
make
Explanation:
A RUN statement creates a new image layer and executes the specified shell command. This means that each RUN statement will run the command in a separate shell, so the current directory from the previous RUN will not be preserved (you can see that the CMake current directory is / by looking closely at the error message).
You can find more info about RUN statement in the Docker documentation and I also recommend reading Best practices for writing Dockerfiles.
I have a Docker container running "FROM arm64v8/oraclelinux:8" , I am running this on a Mac m1 mini using tightvnc.
I want to add a user called "suiteuser" (uid 42065) and in a group called "cvsgroup" (gid 513), inside my docker container, So that when I run the container it starts under my user directly.
Here is my entire Dockerfile-
FROM arm64v8/oraclelinux:8
# Setup basic environment stuff
ENV container docker
ENV LANG en_US.UTF-8
ENV TZ EST
ENV DEBIAN_FRONTEND=noninteractive
# Base image stuff
#RUN yum install -y zlib-devel bzip2 bzip2-devel readline-devel sqlite sqlite-devel openssl-devel vim yum-utils sssd sssd-tools krb5-libs krb5-workstation.x86_64
# CCSMP dependent
RUN yum install -y wget
RUN yum install -y openssl-libs-1.1.1g-15.el8_3.aarch64
RUN yum install -y krb5-workstation krb5-libs krb5-devel
RUN yum install -y glibc-devel glibc-common
RUN yum install -y make gcc java-1.8.0-openjdk-devel tar perl maven svn openssl-devel gcc
RUN yum install -y gdb
RUN yum install -y openldap* openldap-clients nss-pam-ldapd

# Minor changes to image to get ccsmp to build
RUN ln -s /usr/lib/jvm/java-1.8.0-openjdk /usr/lib/jvm/default-jvm

# Install ant 1.10.12
RUN wget https://mirror.its.dal.ca/apache//ant/binaries/apache-ant-1.10.12-bin.zip
RUN unzip apache-ant-1.10.12-bin.zip && mv apache-ant-1.10.12/ /opt/ant
ENV JAVA_HOME /usr
ENV ANT_HOME="/usr/bin/ant"
ENV PATH="/usr/bin/ant:$PATH"
CMD /bin/bash
could anyone please suggest any ideas on how to do this.
Note 1. I know its not advisable to do this directly in the container as, every time you want to make any changes you would have to rebuild it, but this time i want to do this.
To create the group:
RUN groupadd -g 513 cvsgroup
To create the user, as a member of that group:
RUN useradd -G cvsgroup -m -u 42065 suiteuser
And toward the end of Dockerfile, you can set the user:
USER suiteuser
There may be more to do here, though, depending on your application. For example, you may need to chown some of the contents to be owned by suiteuser.
I am Running docker on an M1 Macbook Pro , here i am using this docker script
FROM node:current-buster
# Create and set user
RUN wget https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb
RUN apt-get update && apt install -y ./google-chrome-stable_current_amd64.deb
This throws an error
google-chrome-stable:amd64 : Depends: libasound2:amd64 (>= 1.0.16) but it is not installable
and same for other dependencies
I have tried various ways:
changing base image
changing the installation step to
apt-get install -y wget gnupg ca-certificates procps libxss1 &&
wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | apt-key add - && sh -c 'echo "deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main" >> /etc/apt/sources.list.d/google.list'&&
apt-get update &&
apt-get install -y google-chrome-stable
(This gives an error unable to locate package)
The script runs on a linux machine but for m1 mac it doesnt work.
I actually wanted to run puppeteer inside docker for which i am trying to install chrome incase there is an another way around.
docker buildx build --platform=linux/amd64
This allows us to build the image atleast. Not sure if running it would produce the same result on M1 machine but atleast the image is built
EDIT::
so chrome has no arm image and that was the main cause for this problem changing it to chromium on base ubuntu 18.04 seems to work fine
FROM ubuntu:18.04
RUN apt-get install -y chromium-browser
It should work on both debian and ubuntu, try first to run sudo apt update after that it was able to install arm build of chromium.
I have an already compiled Linux app which has become dated. To use it, I want to create a Docker image and an appropriate environment to work with. My problem is that is app requires an older version of the boost libraries. 1.57.0 to be specific.
I have been able to get boost installed (I believe correctly) but the app errors out.
The error that I am getting is:
undefined symbol: _ZN5boost15program_options3argE
I am hoping someone has experience with this. Briefly, my pipeline is:
get the rocker/verse Docker image that has Debian and R and some more goodies I need.
Bash in to it, apt-get install ... etc.
sudo apt-get update && sudo apt-get upgrade
sudo apt-get install build-essential g++ python-dev autotools-dev libicu-dev build-essential libbz2-dev libboost-all-dev
cd home
wget -O boost_1_57_0.tar.gz https://sourceforge.net/projects/boost/files/boost/1.57.0/boost_1_57_0.tar.gz/download
tar xzvf boost_1_57_0.tar.gz
cd boost_1_57_0
./bootstrap.sh --with-libraries=atomic,chrono,context,coroutine,container,date_time,exception,filesystem,graph,graph_parallel,iostreams,locale,log,math,mpi,program_options,python,random,regex,serialization,signals,system,test,thread,timer,wave
./b2 toolset=gcc cxxflags=-std=gnu++0x
sudo ./b2 install
sudo apt-get update && sudo apt-get upgrade && sudo apt-get dist-upgrade
-----Edit: added additional bash code that was missing here
sudo sh -c 'echo "/usr/local/lib" >> /etc/ld.so.conf.d/local.conf’
I have installed docker on my host virtual machine. And now want to create a file using vi.
But it's showing me an error:
bash: vi: command not found
login into container with the following command:
docker exec -it <container> bash
Then , run the following command .
apt-get update
apt-get install vim
The command to run depends on what base image you are using.
For Alpine, vi is installed as part of the base OS. Installing vim would be:
apk -U add vim
For Debian and Ubuntu:
apt-get update && apt-get install -y vim
For CentOS, vi is usually installed with the base OS. For vim:
yum install -y vim
This should only be done in early development. Once you get a working container, the changes to files should be made to your image or configs stored outside of your container. Update your Dockerfile and other files it uses to build a new image. This certainly shouldn't be done in production since changes inside the container are by design ephemeral and will be lost when the container is replaced.
USE THIS:
apt-get update && apt-get install -y vim
Explanation of the above command
apt-get update => Will update the current package
apt-get install => Will install the package
-y => Will by pass the permission, default permission will set to Yes.
vim => Name of the package you want to install.
Your container probably haven't installed it out of the box.
Run apt-get install vim in the terminal and you should be ready to go.
Add the following line in your Dockerfile then rebuild the docker image.
RUN apt-get update && apt-get install -y vim
Alternatively, keep your docker images small by not installing unnecessary editors. You can edit the files over ssh from the docker host to the container:
vim scp://remoteuser#container-ip//path/to/document
error:: bash: vi: command not found
run the below command by logging as root user to the container--
docker exec --user="root" -it (container ID) /bin/bash
apt-get update
apt-get install vim
Use below command in Debian based container:
apt-get install vim-tiny
Complete instruction for using in Dockerfile:
RUN apt-get update && apt-get install --no-install-recommends -y \
vim-tiny \
&& apt-get clean && rm -rf /var/lib/apt/lists/*
It doesn't install unnecessary packages and removes unnecessary downloaded files, so your docker image size won't increase dramatically.
The most voted answer has the correct idea, however, it did not work in my case. The comment from #java25 did the trick in my case. I had to log into the docker container as a root user to install vim. I am just posting the comment as an answer so that it is easier for others, having the similar problem, to find it.
docker exec -ti --user root <container-id> /bin/bash
Once you are inside docker, run the following commands now to install vi.
apt-get update
apt-get install vim
To install within your Docker container you can run command
docker exec apt-get update && apt-get install -y vim
But this will be limited to the container in which vim is installed.
To make it available to all the containers, edit the Dockerfile and add
RUN apt-get update && apt-get install -y vim
or you can also extend the image in the new Dockerfile and add above command. Eg.
FROM < image name >
RUN apt-get update && apt-get install -y vim
Inside container (in docker, not in VM), by default these are not installed.
Even apt-get, wget will not work. My VM is running on Ubuntu 17.10. For me yum package manager worked.
Yum is not part of Debian or ubuntu. It is part of red-hat. But, it works in Ubuntu and it is installed by default like apt-get
To install vim, use this command
yum install -y vim-enhanced
To uninstall vim :
yum uninstall -y vim-enhanced
Similarly,
yum install -y wget
yum install -y sudo
-y is for assuming yes if prompted for any question asked after doing yum install package-name
error:: bash: vim: command not found
Run the below command by logging as root user to the container:
microdnf install -y vim
If you actually want a small editor for simple housekeeping in a docker, use this in your Dockerfile:
RUN apt-get install -y busybox && ln -s /bin/busybox /bin/vi
I used it on an Ubuntu 18 based docker.
(Of course you might need an RUN apt-get update before it but if you are making your own Docker file you probably already have that.)
Usually changing a file in a docker container is not a good idea. Everyone will forget about the change after a while. A good way is to make another docker image from the original one.
Say in a docker image, you need to change a file named myFile.xml under /path/to/docker/image/. So, you need to do.
Copy myFile.xml in your local filesystem and make necessary changes.
Create a file named 'Dockerfile' with the following content-
FROM docker-repo:tag
ADD myFile.xml /path/to/docker/image/
Then build your own docker image with docker build -t docker-repo:v-x.x.x .
Then use your newly build docker image.
