CentOS-8 - Ceph Nautilus 63 B/s | 38 B 00:00
Error: Failed to download metadata for repo 'centos-ceph-nautilus': Cannot prepare internal mirrorlist: No URLs in mirrorlist
If you need to update your CentOS 8 Stream, you need to change the mirrors to vault.centos.org
Step 1: Go to the /etc/yum.repos.d/ directory
# cd /etc/yum.repos.d/
Step 2: Run the below commands
# sed -i 's/mirrorlist/#mirrorlist/g' /etc/yum.repos.d/CentOS-*
# sed -i 's|#baseurl=http://mirror.centos.org|baseurl=http://vault.centos.org|g' /etc/yum.repos.d/CentOS-*
Now run your dnf command.

I am trying to get mssql working on my OSX machine. However, it keeps giving me error:
$ sqlcmd -S 0.0.0.0,1401 -U SA -P P#55w0rd -i database-setup/sql/initialize.sql
Sqlcmd: Error: Microsoft ODBC Driver 17 for SQL Server : Can't open lib '/usr/local/lib/libmsodbcsql.17.dylib' : file not found.
Although, I am pretty sure, my file is in that location:
$ ls -la /usr/local/lib/libmsodbcsql.17.dylib
lrwxr-xr-x 1 localadmin admin 64 7 4 16:38 /usr/local/lib/libmsodbcsql.17.dylib -> /usr/local/Cellar/msodbcsql17/17.1.0.1/lib/libmsodbcsql.17.dylib
$ ls -la /usr/local/Cellar/msodbcsql17/17.1.0.1/lib/libmsodbcsql.17.dylib

I know this question has been asked multiple times but none of the available solutions have worked for me.
Things I have tried:
https://github.com/Microsoft/homebrew-mssql-release/issues/7
https://github.com/Microsoft/homebrew-mssql-release/issues/3
I fixed my problem by:
$ brew uninstall msodbcsql17 mssql-tools
and then:
$ brew install msodbcsql17 mssql-tools
For me this solved it:
brew install microsoft/mssql-release/msodbcsql17
Here's my Dockerfile:

I can run the app:
$ docker run -d -P --name myapp jacobirr/pleromatest
And see tcp port 80:
$ docker port myapp
80/tcp -> 0.0.0.0:32769
Here's my requirements.txt:
Flask==0.10.1
Flask-Restless==0.13.1

python-mimeparse==0.1.4
requests==1.2.3
six==1.3.0
wsgiref==0.1.2
setuptools==5.4.2
mod_wsgi==4.5.15
Why can't I get to localhost:32769 in the browser? I suspect this is related to:
•the user/group running apache?
•the fact that I'm installing mod_wsgi but it's nowhere on the docker "filesystem" so I have to use mod_wsgi-express?
Update:
'1' Netstat shows:

'2' httpd seems to be running in my container:

From all your outputs, your httpd / uwsgi process is definitely bound to 8000, and this is the port you need to expose on the container.
This line in netstat, is showing a bind on 8000, and nothing else.
tcp 0 0 *:irdmi *:* LISTEN
It is not obvious here, but if you use the --numeric-ports argument, it will not convert the 8000 into its known port.
In your docker file, again you should
EXPOSE 8000
When launching your container, you can also specify the port to use on the host machine:
docker run -p 8080:8000 --name ...
After this, you should be able to use your browser to hit
localhost:8080 -> container:8000
Add this to your Dockerfile, just before CMD:
WORKDIR /usr/src/app/
Assuming that your start-apache-server file is in that directory. This will help wsgi to find the needed file.
docker started to produce weird bugs when I was using a few simple alpine based containers. Two of these problems are:
rc-update was not found when i was trying to use it
after installing openssh package, there was nothing in /etc/ssh or there was no /etc/init.d/sshd to start/restart the service
To avoid confusion I checked out a widely used container that serves as a simple SSH server. You can do it by executing:
git clone https://github.com/chamunks/alpine-openssh.git
After this go into the alpine-openssh directory and build the container with:
docker build -t alpine-openssh .
Mine produces the following:

Notice the /bin/sh: rc-update: not found part. This should work but it doesn't. I restarted my docker service, checked out docker's forums but no similar issue has been reported so far.
Any ideas why does it happen?
The rc-update tool is a part of the openrc package which is not included in the base image.
apk add openrc
I made a Fedora backup, then used Windows 7 for some time and tried to install Fedora back using dd command (under live cd), but now, it loads with black screen and says to look to journal: journalctl.
There are errors: fsck failed with error code 8; Failed to mount /sysroot and so on.
The commands I used:
sudo dd if=/dev/sda bs=1M conv=noerror | gzip > OS.gz
sudo dd if=OS.gz bs=1M conv=noerror | gunzip > /dev/sda
sudo partprobe /dev/sdaY
sudo tune2fs -U random /dev/sdaY
What do I need to do to reinstall Fedora using existing backup?
I created the Dockerfile below and I tried to build the docker file but it's stop in Step 7 with below issue.
