Dockerfile multiple CMD directives

Please remove duplicate CMD directives from Python/AppDev/Dockerfile

CMD ["ufw allow 5000"] .. this is just ignored, only last CMD is executed.

Why would you try to execute ufw inside a container? It's not available.

BTW directive MAINTAINER is depreciated.

issue with https://dcloud-dna-center-inst-rtp.cisco.com

cannot connect, related to a PR that is ope

Python/AppDev/app/myApi.py

This script actually fails to search beyond first entry in db.txt.
I've wasted 15 mins figuring out what's wrong, instead of learning :).

As you can see below, if first record is match, OK found.
If 1st record is not match, it will return with "No match".
2nd record is never tried, function never continues looping, it returns after validation of 1st record...

for record in records:
                if record['hostname'] == hostname:
                    LOG.info('Routers returned')
                    return jsonify(record), 200
                if record['hostname'] != hostname:
                    LOG.warning('No matching router')
                    return jsonify({"response": "No match"}), 200

I did modify your script to work:

@app.route('/routers', methods=['GET'])
def getRouter():
    try:
        hostname = request.args.get('hostname')
        if (hostname is None) or (hostname == ""):
            LOG.warning('No hostname specified')
            raise ValueError
        with open(f'{script_dir}/db.txt', 'r') as f:
            data = f.read()
            records = json.loads(data)
            for record in records:
                print("Hostname: ", record['hostname'])
                if record['hostname'] == hostname:
                    LOG.info('Routers returned')
                    return jsonify(record), 200
                if record['hostname'] != hostname:
                    continue    
                    
            LOG.warning('No matching router')
            return jsonify({"response": "No match"}), 200
    except ValueError:
        LOG.error("NO HOSTNAME SPECIFIED")
        return jsonify({"error": "NO_HOSTNAME_SPECIFIED"}), 400
    except Exception as err:
        LOG.error(f'Error during GET {err}')
        return jsonify({"error": err}), 500

Creating the repository gives an error in file installAnsible.py

Hello Knox,

First of all thank you for your clear instructions on CBT-nuggets!

I ran into an issue when I wanted to install ansible.
When I pasted in "sudo apt-add-repository ppa: ansible/ansible" I got the message "Error: need a single repository as argument". I searched online and came with an solution that helped me: between ppa: ansible/ansible there has to be no spaces in order to work. It worked for me when I used the command "sudo apt-add-repository ppa:ansible/ansible"

Kind regards.
