Can ejabberd be installed on Google Compute Engine? Will there be any issues with using ejabberd on Compute Engine? I have looked but cannot find any references to anyone trying this before. Grateful for any help.
Yes. Compute Engine gives you VMs. You can put whatever you want on them, such as Erlang and ejabberd.
Yes you can.
You can use the Vm with Debian Image and follow this intructions.

dont forget open the ports in the firewall.
Sorry I didn't have much time to put together a cleaner "how to". I just copied and pasted from my personal archive.
Here's what you'd have to do to compile the source code on a Compute Engine. Please let me know if you have any questions.

Title is pretty self explanatory, when using yum upgrade curl it doesn't upgrade curl beyond 7.29.0 witch is an issue because I need to use the --retry-all-errors flag in the docker images startup script.
Running the below commands solved my issue
sudo rpm -Uvh http://www.city-fan.org/ftp/contrib/yum-repo/rhel7/x86_64/city-fan.org-release-2-2.rhel7.noarch.rpm
sudo yum install -y yum-utils
sudo yum-config-manager --disable city-fan.org
sudo yum -y --enablerepo=city-fan.org install libcurl libcurl-devel
If using the city-fan repo is an issue for you, you can also use this script to install directly from curl.
sudo yum install wget gcc openssl-devel make -y
wget https://curl.haxx.se/download/curl-${VERSION}.tar.gz
tar -xzvf curl-${VERSION}.tar.gz
rm -f curl-${VERSION}.tar.gz
cd curl-${VERSION}
./configure --prefix=/usr/local --with-ssl
make
sudo make install
sudo ldconfig
I use the following Dockerfile to build an image and start a container. But once I am in the container, I still can not find manpages. Does anybody know how to solve this problem?
$ cat Dockerfile
FROM ubuntu
RUN apt -y update && apt -y upgrade
RUN apt-get -y install build-essential
RUN apt-get -y install vim
RUN apt-get -y install man
RUN apt-get -y install gawk
RUN apt-get -y install mawk
$ man man
No manual entry for man
See 'man 7 undocumented' for help when manual pages are not available.
$ find /usr/share/man /usr/local/share/man -type f
You need to make a change to your /etc/dpkg/dpkg.cfg.d/excludes within the container. You can do this in your Dockerfile with the following command:
RUN sed -i 's:^path-exclude=/usr/share/man:#path-exclude=/usr/share/man:' \
/etc/dpkg/dpkg.cfg.d/excludes
Then make another update to your Dockerfile to install the man pages
RUN apt-get update && \
apt-get install -y \
man \
manpages-posix
There is a easier way to enable the MAN command.
In terminal, just execute the command below:
unminimize
It will ask if you like to continue [Y/n]
Just press:
Y
It will take a while to finish all the processing.
After that, test this:
man man
Simple as that

I was trying many ways in order to install Erlang 17.3 on Ubuntu 18. So far I came up with this solution you can read below:
For installation Erlang 17.3 on Ubuntu 18 you should do the following things:
Enter in the console next command:
Download the tar file:
wget http://erlang.org/download/otp_src_17.3.tar.gz
Extract the tar file in directory where you download the otp_src_17.3.tar.gz:
cd '/home/yaroslav/otp_src_17.3'
tar -zxf otp_src_17.3.tar.gz
set export ERL_TOP your 'pwd' path:
export ERL_TOP=pwd
Basic dependencies:
sudo apt-get install autoconf libncurses-dev build-essential
Other applications dependencies
sudo apt-get install m4
sudo apt-get install unixodbc-dev
sudo apt-get install libssl-dev
sudo apt-get -y install libssh-dev
sudo apt-get install libwxgtk3.0-dev libglu-dev
sudo apt-get install fop xsltproc
sudo apt-get install g++
sudo apt-get install default-jdk
sudo apt-get install xsltproc fop
Or all dependencies in one line:
apt-get -y install build-essential autoconf m4 libncurses5-dev libwxgtk3.0-dev libgl1-mesa-
dev libglu1-mesa-dev libpng-dev libssh-dev unixodbc-dev xsltproc fop g++ default-jdk
install openssl version 1.0.2 for Ubuntu 18 (different version SSL is not compatible):
curl https://www.openssl.org/source/openssl-1.0.2l.tar.gz | tar xz && cd openssl-1.0.2l &&
sudo ./config && sudo make && sudo make install
Configure and build:
./configure --with-ssl='/home/yaroslav/otp_src_17.3/openssl-1.0.2l'
sudo make
sudo make install
For installing older versions of Erlang and working with several at the same time I would recommend using kerl
If you need more fancy features you could also head for asdf which has a Erlang plugin (which runs kerl under the hood)
I have this in a Dockerfile:
RUN apt install -y python3-pip
how do I install a specific version of python though? Something like this:
RUN apt install -y python3-pip#python===3.6.7
I am looking for:
Python 3.6.7
If you want to install latest version just use RUN apt-get install python3 but if you want to install specific version of python you should do it manually for example were going to install python3.5.1:
sudo apt-get install libssl-dev openssl
wget https://www.python.org/ftp/python/3.5.1/Python-3.5.1.tgz
tar xzvf Python-3.5.1.tgz
cd Python-3.5.1
./configure
make
sudo make install
After installation completed set installed python as default one.
If you just want to install a specific version of Python over a simple Ubuntu, then why don't you directly use the official Python image corresponding to your needs ?
You can find all the supported images here : https://hub.docker.com/_/python
