I'm working on a personal project that requires me to do some bash scripting. I am currently trying to write a script that pulls from my private git repo. At the moment I am able to spin up my instance and install all my packages through a script. But when it comes to pulling from my private repo I get The authenticity of host 'github.com (192.30.253.113)' can't be established
I am trying to figure out a way to pass "yes" with my script. I know this is very bad practice but for my current use case, I'm not too concerned about security.
running this ssh-keyscan github.com >>~/.ssh/known_hosts command manual works, but when I put this in my script it does not seem to work.
Any help would be greatly appreciated
My script:
echo "update install -start"
sudo yum -y update
sudo amazon-linux-extras install -y lamp-mariadb10.2-php7.2 php7.2
sudo yum install -y httpd mariadb-server
sudo yum install -y git
sudo systemctl start httpd
echo "end"
#file premissions
sudo usermod -a -G apache ec2-user
sudo chown -R ec2-user:apache /var/www
sudo chmod 2775 /var/www && find /var/www -type d -exec sudo chmod 2775 {} \;
#pulling from my git repo
ssh-keyscan github.com >>~/.ssh/known_hosts
cd ../../var/www/html/
git clone git#github.com:jackbourkemckenna/testrepo

Hello I'm trying to create a ruby app using the user id and group id in the container as in the host, ie. 1000.
I run into permissions problems but I can't figure out why.
Here is the error that I get:
There was an error while trying to write to `/home/appuser/myapp/Gemfile.lock`.
It is likely that you need to grant write permissions for that path.
The command '/bin/sh -c bundle install' returned a non-zero code: 23
Here is my Dockerfile:
# Dockerfile
FROM ruby:2.5
RUN apt-get update -qq && apt-get install -y build-essential libpq-dev nodejs
RUN groupadd -r -g 1000 appuser
RUN useradd -r -m -u 1000 -g appuser appuser
USER appuser
RUN mkdir /home/appuser/myapp
WORKDIR /home/appuser/myapp
COPY Gemfile Gemfile.lock ./
RUN bundle install
COPY . ./
If you want a pure docker solution, try this:
FROM ruby:2.5
RUN apt-get update -qq && apt-get install -y build-essential libpq-dev nodejs
# Reduce layers by grouping related commands into single RUN steps
RUN groupadd -r -g 1000 appuser && \
useradd -r -m -u 1000 -g appuser appuser
# Setting workdir will also create the dir if it doesn't exist, so no need to mkdir
WORKDIR /home/appuser/myapp
# Copy everything over in one go
COPY . ./
# This line should fix your issue
# (give the user ownership of their home dir and make Gemfile.lock writable)
# Must still be root for this to work
RUN chown -R appuser:appuser /home/appuser/ && \
chmod +w /home/appuser/myapp/Gemfile.lock
USER appuser
RUN bundle install
Might be a better idea to fix the permissions on your host system with something like this:
sudo chmod g+w Gemfile.lock
below is code preview
function f1{
sudo su -
cd /root
yum install expect -y
wget <some url>
}
ssh ec2-user#<ip> -i <key> "$(typeset -f f1); f1"
when I am running this script. It is hanging. I think it is not switching to root and executing rest of lines.
Can somebody help me to make it work.
I am trying to use a post shell script to copy the directory of an apache website into a vagrant box using packer but Im not sure what directory I should put the directory that contains all the files for apache. I keep running into this error:

Any file on the host machine doesn't automatically get transfered to the guest. You need to use file provisioner to upload bootstrap-website.

I can build the image successfully but when I try to run the container I get this error:
$ docker run mybuild
no such file or directory
Error response from daemon: Cannot start container 3e8aa828909afcd8fb82b5a5ac894
97a537bef2b930b71a5d20a1b98d6cc1dd6: [8] System error: no such file or directory
what does it mean 'no such file or directory'?
Here is my simple script:
#!/bin/bash
sudo service mongod start
mvn clean verify
sudo service mongod stop
I copy it like this: COPY build-script /build-script
and run it like this: CMD ["/build-script"] not sure why its not working
Using service isn't going to fly - the Docker base images are minimal and don't support this. If you want to run multiple processes, you can use supervisor or runit etc.
In this case, it would be simplest just to start mongo manually in the script e.g. /usr/bin/mongod & or whatever the correct incantation is.
BTW the lines where you try to clean up don't have much effect:
RUN rm -f /tmp/apache-maven-3.2.2.tar.gz
...
# remove download archive files
RUN apt-get clean
These files have already been committed to a previous image layer, so doing this doesn't save any disk-space. Instead you have to delete the files in the same Dockerfile instruction in which they're added.
Also, I would consider changing the base image to a Java one, which would save a lot of work. However, you may have trouble finding one which bundles the official Oracle JDK rather than OpenJDK if that's a problem.
I'm trying to setup Vagrant virtual machines to support my learning through Seven Databases in Seven Weeks. I'm provisioning software using basic shell scripts which performs appropriate actions within a sudo environment. However, I'm using the vagrant user to run the tutorials, and would like the provisioning to install the appropriate node / NPM modules as Vagrant, rather than through sudo.
My current npm command is the last line in this provisioning script, but the module is unavailable when vagrant tried to execute node scripts.

Simply set privileged to false in your VagrantFile like this:
Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
...
config.vm.provision :shell, privileged: false, path: "script.sh"
...
end
The shell provision runs as the root user. If you with to run as the vagrant user, you can do something like this:
sudo -u vagrant npm install hiredis redis
..or for multiple lines:
sudo -u vagrant << EOF
[...]
npm install hiredis
npm install redis
EOF
Maybe use npm install -g to install it globally in the vm?
