Installation of debian file failing in Grafana - grafana

I've got a custom built grafana docker image that I build using
go run build.go build package
This all works fine, and I get a deb image from the process (grafana_4.3.0-1490275845pre1_amd64.deb) as well as a .tar.gz file and an rpm package as well.
When using the dockerfile (essentially copied from grafana/grafana-docker):
FROM debian:jessie
COPY ./grafana.deb /tmp/grafana.deb
RUN apt-get update && \
apt-get -y --no-install-recommends install libfontconfig curl ca-certificates && \
apt-get clean && \
dpkg -i --debug=3773 /tmp/grafana.deb && \
rm /tmp/grafana.deb && \
I get the following error:
dpkg (subprocess): unable to execute installed post-installation script (/var/lib/dpkg/info/grafana.postinst): No such file or directory
dpkg: error processing package grafana (--install):
subprocess installed post-installation script returned error exit status 2

D000002: fork/exec /var/lib/dpkg/info/systemd.postinst ( triggered /etc/init.d )
D000001: ensure_diversions: same, skipping
Errors were encountered while processing:
grafana
Setting up grafana (4.3.0-1490275845pre1) ...
Processing triggers for systemd (215-17+deb8u6) ...
The command '/bin/sh -c apt-get update && apt-get -y --no-install-recommends install libfontconfig curl ca-certificates && apt-get clean && dpkg -i -- debug=3773 --force-all /tmp/grafana.deb && rm /tmp/grafana.deb && curl -L https://github.com/tianon/gosu/releases/download/1.7/gosu-amd64 > /usr/sbin/gosu && chmod +x /usr/sbin/gosu && apt-get remove -y curl && apt-get autoremove -y && rm -rf /var/lib/apt/lists/*' returned a non-zero code: 1
The obvious issue is (/var/lib/dpkg/info/grafana.postinst): No such file or directory but not knowing anything about dpkg I don't really know where to start trying to debug it. As far as I'm aware, I've not altered the deployment scripts so I'm at a loss to know where the issue has arisen.

As I was developing Grafana on a shared Windows folder, with Grafana running in a Docker container on VirtualBox, it seems that (despite not editing the files) SourceTree or something else edited the source to add Windows new lines which messed up the packaging step. I just used dos2unix to remove newlines and everything started working as expected.
The particular error message was related to newlines in the postinst file, which I debugged manually with bash on the VM.

how to run an app with flutter-pi from a docker container

I'm running a flutter app on a raspberry pi 4, I'm using flutter-pi. Everything works fine, but I want to take it to a higher level.
I want to encapsulate the app and all flutter-pi dependencies in a docker container.
I am using the ubuntu:jammy image as a base, I have installed all the dependencies according to flutter-pi.
When I run the app I get this error:
[locales] Warning: The system has no configured locale. The default "C" locale may or may not be supported by the app.
[keyboard] Could not load keyboard configuration from "/etc/default/keyboard". Default keyboard config will be used. load_file: No such file or directory
[flutter-pi] Could not query DRM device list: No such file or directory
NOTE: the raspberry is configured to do a console auto login and does not have a graphical interface
I have developed a flutter-pi application and encapsulated it in a container.
What I noticed is that this error (Could not query DRM device list: No such file or directory) happens to me only sometimes, the configuration is always the same but sometimes I faced it and some times I didn't.
I'm assuming it is related with the host system in which the docker containers are running, because as I previously said the configuration of the container is always the same in both the working container and the not working one.
I'm attaching down below the configuration of my dockerfile (it's made of 2 dockerfiles but it's only 1 container that I'm running, the second dockerfile uses the first one which is built in emotionsrl/tower-display-base).
The display_launcher.py only runs the flutter (flutter-pi --release ./spotlink_build) after a few checks that are not related with the rest.

i am creating an ECS cluster with docker image library/wordpress:latest and i get the desired task in running state but when i build this image using following Dockerfile and push it to my dockerhub repo and then try to create this cluster using my new image the containers fails by giving Exit code 2
Could you please suggest me what am i doing wrong here?

i am basically just trying to run a script into the container
I used a worpress image and built my own image out of it, thought it would keep the container up and my script will be executed but that didnt happen. My ECS cluster didnt have any running task, all i saw iin the events was service stage-fe-auto has started 1 tasks: task e83587e734c94f77. and when i opened the task details, it had Exit Code 2 and Working directory /home/app but in my Dockerfile my work directory is differen. Not sure what i did wrong

mongo inside ansible-operator image

I need the mongo shell installed inside the ansible-operator image.
My first attempt was to use this Dockerfile:
FROM mongo:4.2.9
FROM quay.io/operator-framework/ansible-operator:v1.0.0
COPY --from=0 /usr/bin/mongo /usr/bin/mongo
COPY requirements.yml ${HOME}/requirements.yml
RUN ansible-galaxy collection install -r ${HOME}/requirements.yml \
&& chmod -R ug+rwx ${HOME}/.ansible
COPY watches.yaml ${HOME}/watches.yaml
COPY roles/ ${HOME}/roles/
COPY playbooks/ ${HOME}/playbooks/
Unsurprisingly, this didn't worked.
"stderr_lines": ["/usr/bin/mongo: /lib64/libcurl.so.4: no version information available (required by /usr/bin/mongo)", "Failed global initialization: InvalidSSLConfiguration Can not set up PEM key file."]
Can anyone help me?
I finally figured it out...
Just add this to your Dockerfile.
(mongodb-org-4.2.repo)
USER 0
COPY mongodb-org-4.2.repo /etc/yum.repos.d/mongodb-org-4.2.repo
RUN yum -y update \
&& yum install -y mongodb-org-shell \
&& yum clean all \
&& rm -rf /var/cache/yum
RUN rm /etc/yum.repos.d/mongodb-org-4.2.repo
USER ${USER_UID}

PowerShell Core in Debian Docker Container Error

I'm new to Docker and am trying to create a Docker image with Raspbian base and PowerShell Core installed.
EDIT: Updated Dockerfile to include libicu52 package, which resolved the main error: lack of libpsl-native or dependencies not available. Changed CMD parameters and now have a different error.
Here is my Dockerfile:
# Download the latest RPi3 Debian image
FROM resin/raspberrypi3-debian:latest
# Update the image and install prerequisites
RUN apt-get update && apt-get install -y \
wget \
libicu52 \
libunwind8 \
&& apt-get clean
# Grab the latest tar.gz
RUN wget https://github.com/PowerShell/PowerShell/releases/download/v6.0.0-rc.2/powershell-6.0.0-rc.2-linux-arm32.tar.gz
# Make folder to put PowerShell
RUN mkdir ~/powershell
# Unpack the tar.gz file
RUN tar -xvf ./powershell-6.0.0-rc.2-linux-arm32.tar.gz -C ~/powershell
# Run PowerShell
CMD pwsh -v
New error:
hostname: you must be root to change the host name
/bin/sh: 1: pwsh: not found
How do I resolve these errors?
Thanks in advance!
Instead of downloading from source and extracting it in your container, I'd recommend using the official apt installer packages for your Dockerfile from Microsoft's official Debian repository as described at:
https://learn.microsoft.com/en-us/powershell/scripting/setup/installing-powershell-core-on-macos-and-linux?view=powershell-6#debian-9
So transforming that to Dockerfile format:
# Install powershell related system components
RUN apt-get install -y \
gnupg curl apt-transport-https \
&& apt-get clean
# Import the public repository GPG keys
RUN curl https://packages.microsoft.com/keys/microsoft.asc | sudo apt-key add -
# Register the Microsoft's Debian repository
RUN sh -c 'echo "deb [arch=amd64] https://packages.microsoft.com/repos/microsoft-debian-stretch-prod stretch main" > /etc/apt/sources.list.d/microsoft.list'
# Install PowerShell
RUN apt-get update \
&& apt-get install -y \
powershell
# Start PowerShell
CMD pwsh
Alternatively you can also try to start from one of the original Microsoft docker Linux images, but of course then you need to solve then the raspberry installation for yourself:
https://hub.docker.com/r/microsoft/powershell/tags/

Can you please suggest self-hosted system with code snippets tagging?

For Example:
Sys-admin installed Oracle JDK on Ubuntu - it is about 5 lines bash commands:
sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
echo oracle-java8-installer shared/accepted-oracle-license-v1-1 select true | sudo /usr/bin/debconf-set-selections
sudo apt-get install -y oracle-java8-installer
sudo apt-get install oracle-java8-set-default
We would need to save those commands as bash code snippet and tag them as "Oracle JDK". Or for example PostgreSQL installation or any other stuff System team do repeatedly and need to find it quickly for quick revision
Please? any advise?
CoderVault appears to be a good solution for teams doing all kinds of code snippets: https://github.com/codervault/codervault
If you want it directly in Bash, you would need to cook up some own form of snippet file, source it and sync it. For example, create a folder .functions and a file ~/.functions/shared with the following content:
# Setup, do not change
alias sniplist="awk '/function/ {print $2;}' ~/.functions/shared"
function syncSnippets {
P=$(pwd) && \
cd ~/.functions && \
git pull --rebase <HOST>/path/to/repo && \
cd $P
source ~/.functions/shared
}
# Add snippets below
function OracleJDK {
sudo add-apt-repository ppa:webupd8team/java && \
sudo apt-get update && \
echo oracle-java8-installer shared/accepted-oracle-license-v1-1 select true | sudo /usr/bin/debconf-set-selections && \
sudo apt-get install -y oracle-java8-installer && \
sudo apt-get install oracle-java8-set-default
}
Add more functions as needed. The && is for running all commands in sequence and aborting when one of them fails, \ for being able to continue the same command on another line. This way, you're going to run a single chained command.
Create a Git repository (git init), add a server (git remote add origin <HOST>/path/to/repo), commit and push. Remember: you don't need a Git server to host a repository. You could just init it on the server and have it accessible by SSH, that's all you need.
All anyone else needs to do is clone this repo (git clone <HOST>/path/to/repo ~/.functions), source it in the shell config file (source ~/.functions/shared) and start another shell. Done.
Should you ever forget which snippets are available, just run sniplist and get a handy shortlist of functions.
