I am using docker for a Python application.
FROM python:3.5-slim
WORKDIR /abc
ADD . /abc
RUN apt-get update && \
apt-get install -y --no-install-recommends \
curl \
gcc \
python3-dev \
musl-dev \
&& \
pip install -r requirements.txt &&\
apt-get clean && \
rm -rf /var/lib/apt/lists/* &&\
apt-get purge -y --auto-remove gcc
So whenever I am running the docker build command it first runs the apt-get update command there.
With update command, it's also downloading many recommended packages and taking long build time.
How can I stop Ubuntu from installing recommended packages and build docker faster?
Note: In the Dockerfile, apt-get --no-install-recommends update is not working; it's still downloading packages.
apt-get update should not install anything. The only thing apt-get update should do is update the local description of what packages are available. That does not download those packages though -- it just downloads the updated descriptions. That can take a while.
apt-get install will of course install packages. In order to install those packages, it needs to download them. Using --no-install-recommends tells apt-get to not install "recommended packages". For example, if you install vim, there are many plugins that are also recommended and provided as separate packages. With that switch, those vim plugins will not be installed. Of course, installing the packages you selected can also take a while.
What you're doing, using && \ is to put all of that into a single docker command. So every time you rebuild your image, you will have to do that every time because the list of packages changes every day, sometimes even multiple times per day.
Try moving pip install -r requirements.txt to its own RUN command after you've run apt-get stuff. If that then does what you want, then I suggest reading and learning more about how Docker works under the hood. In particular, it's important to understand how each single command adds a new layer and how any dynamic information in a single layer can cause long build times because the layer will frequently change with large amounts of changes.
Additionally, you might want to move ADD . /abc to after the RUN commands. Any changes you've made to the files being added (source code, I assume) will invalidate the layer which represents the apt-get command that has been executed. Since it's been invalidated, it will need to be rebuilt. If you're actively working on and developing those projects, that can easily cause apt-get to be executed every time you build your image.
There are plenty of resources you can search for which discuss how to optimize your time when using Docker. I won't recommend any specific one and will leave it to you for learning.
I have these commands in a Dockerfile:
RUN apt-get -y update #1
RUN apt-get -y install sudo #2
RUN sudo apt-get -y update #3
RUN sudo apt-get -y upgrade #4
RUN sudo apt-get install -y sqlite3 libsqlite3-dev #5
It looks as though Docker cannot cache line #3 or #4
Is there a way I can allow Docker to cache those results somehow? It's taking a minute or two to update/upgrade every time the image is built and I'd like to reduce this delay.
First thing You should avoid RUN apt-get upgrade or dist-upgrade, as many of the “essential” packages from the base images won’t upgrade inside an unprivileged container. If a package contained in the base image is out-of-date, you should contact its maintainers.
I think you need to run apt-get update only once within the Dockerfile & Always combine RUN apt-get update with apt-get install in the same RUN statement like
RUN apt-get update && apt-get install -y \
sudo \
sqlite3 \
libsqlite3-dev
I've uninstalled docker with the following command
sudo apt-get purge docker-engine
sudo apt-get autoremove --purge docker-engine
The above command works fine, no problem. But when I try to run sudo rm -rf /var/lib/docker as instructed in Docker docs, I get the following error
rm: cannot remove '/var/lib/docker/aufs/mnt/04fc3de09910bf8fae3d0430b0debbf3032d480bef4ced9f40b1f532bf478ef9': Is a directory
What should I do to remove this content?
First remove docker-engine using sudo apt remove docker-engine
Reboot.
Then remove /var/lib/docker/aufs with sudo rm -rf /var/lib/docker/aufs.
Perform the Ubuntu upgrade with sudo do-release-upgrade
You can now re-install docker-engine using sudo apt install docker-engine (or don't, your choice)
Try sudo su and then rm -rf /var/lib/docker/aufs/mnt/04fc3de09910bf8fae3d0430b0debbf3032d480bef4ced9f40b1f532bf478ef9
I'm trying to autoinstall libpam-ldap with a script, but its not working properly. As now I have
apt-get install libpam-ldap -y
That's alright, but then it goes into another window after answering Y to a continue question, and inside there I have to fill out IPs and other stuff. How can I skip through this? How can I echo "Enter" so I can skip through this?
Please try following
sudo DEBIAN_FRONTEND=noninteractive apt-get install -qq libpam-ldap
However using -qq is discouraged (check man apt-get) so try with '-q'
Anyways important for you is DEBIAN_FRONTEND=noninteractive
How do you uninstall node.js using the cmd line in linux?
For Ubuntu 12.04:
sudo apt-get remove nodejs
This will uninstall nodejs as well as npm.
Edit: If you know which package manager was used to install, it is best to uninstall with the same package manager. Examples for apt, make, yum are in other answers.
This is a manual approach:
Running which node will return something like /path/bin/node.
Then run cd /path
This is all that is added by Node.JS.
rm -r bin/node bin/node-waf include/node lib/node lib/pkgconfig/nodejs.pc share/man/man1/node.1
Now the only thing I don't know about is npm and what it has installed. If you install npm again into a custom path that starts off empty, then you can see what it adds and then you will be able to make a list for npm similar to the above list I made for node.
If you installed from source, you can issue the following command:
sudo make uninstall
If you followed the instructions on https://github.com/nodejs/node/wiki to install to your $HOME/local/node, then you have to type the following before the line above:
./configure --prefix=$HOME/local/node
Sorry the answer of George Bailey does work very fine when you
want absolutely remove the node from your machine.
This answer is referred from : #tedeh
https://github.com/nodesource/distributions/issues/486
If you wanna install a new version of node you have to use the code below
sudo rm -rf /var/cache/yum
sudo yum remove -y nodejs
sudo rm /etc/yum.repos.d/nodesource*
sudo yum clean all
And add new nodejs version to "yum" an new version of node
#using this command for Node version 8
curl --silent --location https://rpm.nodesource.com/setup_8.x | sudo bash -
#using this command for Node version 10
curl --silent --location https://rpm.nodesource.com/setup_10.x | sudo bash -
Install nodejs
sudo yum -y install nodejs
I hope it gonna help you guy!!!
To uninstall node I followed the accepted answer by #George, as I no longer have the sources, but before doing so I ran:
sudo npm rm npm -g
That seemed to get rid of npm from the system directories such as /usr/bin/npm and /usr/lib/npm. I got the command from here. I then found a ~/.npm directory, which I deleted manually. Honestly I don't know if every trace of npm has been removed, but I can't find anything else.
If you installed node using curl + yum:
sudo curl --silent --location https://rpm.nodesource.com/setup_4.x | bash -
sudo yum -y install nodejs
Then you can remove it using yum:
sudo yum remove nodejs
Note that using the curl script causes the wrong version of node to be installed. There is a bug that causes node v6.7 to be installed instead of v4.x intended by the path (../setup_4.x) used in the curl script.
This is better to remove NodeJS and its modules manually because installation leaves a lot of files, links and modules behind and later it create problems while we reconfigure another version of NodeJS and its modules.
Run the following commands.
sudo rm -rf /usr/local/bin/npm /usr/local/share/man/man1/node* /usr/local/lib/dtrace/node.d ~/.npm ~/.node-gyp /opt/local/bin/node opt/local/include/node /opt/local/lib/node_modules
sudo rm -rf /usr/local/lib/node*
sudo rm -rf /usr/local/include/node*
sudo rm -rf /usr/local/bin/node*
and this done.
A step by step guide with commands is at http://amcositsupport.blogspot.in/2016/07/to-completely-uninstall-node-js-from.html
This helped me resolve my problem.
I think Manoj Gupta had the best answer from what I'm seeing. However, the remove command doesn't get rid of any configuration folders or files that may be leftover. Use:
sudo apt-get purge --auto-remove nodejs
The purge command should remove the package and then clean up any configuration files. (see this question for more info on the difference between purge and remove). The auto-remove flag will do the same for packages that were installed by NodeJS.
See the accepted answer on this question for a better explanation.
Although don't forget to handle NPM! Josh's answer covers that.
The answer of George Bailey works fine.
I would just add the following flags and use sudo if needed:
sudo rm -rf bin/node bin/node-waf include/node lib/node lib/pkgconfig/nodejs.pc share/man/man1/node
if you want to just update node, there's a neat updater too
https://github.com/creationix/nvm
to use,
git clone git://github.com/creationix/nvm.git ~/.nvm
source ~/.nvm/nvm.sh
nvm install v0.4.1
I think this works, at least partially (have not investigated):
nvm uninstall <VERSION_TO_UNINSTALL>
eg:
nvm uninstall 4.4.5
If you have yum you could do:
yum remove nodesource-release* nodejs
yum clean all
And after that check if its deleted:
rpm -qa 'node|npm'
after installing using the "ROCK-SOLID NODE.JS PLATFORM ON UBUNTU" script, i get this output. Which tells you how to uninstall nodejs.
Done. The new package has been installed and saved to
/tmp/node-install/node-v0.8.19/nodejs_0.8.19-1_i386.deb
You can remove it from your system anytime using:
dpkg -r nodejs
Best way to go around this is to do it right from the BEGINNING:
INSTALL BREW
#HERE IS HOW: PASTE IN TERMINAL
sudo apt-get install build-essential curl git m4 ruby texinfo libbz2-dev libcurl4-openssl-dev libexpat-dev libncurses-dev zlib1g-dev
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/linuxbrew/go/install)"
Then at the end of your .bashrc file(In your home directory press Ctrl + H)
export PATH="$HOME/.linuxbrew/bin:$PATH"
export MANPATH="$HOME/.linuxbrew/share/man:$MANPATH"
export INFOPATH="$HOME/.linuxbrew/share/info:$INFOPATH"
Then restart terminal so the modification to .bashrc are reloaded
TO INSTALL NODE
brew install node
TO CHECK VERSION
node -v
npm -v
TO UPDATE NODE
brew update
brew upgrade node
TO UNINSTALL NODE
brew uninstall node
To Remove nodejs installed in centos 8:
From your home directory, run the below command
sudo yum remove nodejs
Enter y to confirm your command
In addition to apt or yum removal, clean any residual files to avoid conflicts if you ever install a new version:
sudo rm -rf /usr/local/bin/npm
sudo rm -rf /usr/local/share/man/man1/node*
sudo rm -rf /usr/local/lib/dtrace/node.d
sudo rm -rf ~/.npm
sudo rm -rf ~/.node-gyp
sudo rm -rf /opt/local/bin/node
sudo rm -rf opt/local/include/node
sudo rm -rf /opt/local/lib/node_modules
sudo rm -rf /usr/local/lib/node*
sudo rm -rf /usr/local/include/node*
sudo rm -rf /usr/local/bin/node*
For Centos 7 and 8
Remove NodeJS
sudo yum remove -y nodejs
sudo rm -rf /var/cache/yum
sudo rm /etc/yum.repos.d/nodesource*
sudo yum clean all
Remove residual files
whereis node
sudo rm -rfv /usr/bin/node /usr/local/bin/node /usr/share/man/man1/node.1.gz
sudo rm -rfv /usr/bin/npm /usr/local/bin/npm /usr/share/man/man1/npm.1.gz
sudo rm -rfv /usr/local/bin/npx
sudo rm -rfv /usr/local/lib/node*
sudo rm -rfv /usr/local/include/node*
sudo rm -rfv /usr/lib/node_modules/
Just remove these files. No need to do anything else.
rm -rf ~/.nvm
rm -rf ~/.npm
rm -rf ~/.bower
