Αφού έχουμε εγκαταστήσει τα απαραίτητα προγράμματα δημιουργούμε το Makefile το οποίο θα περιέχει τις εντολές δημιουργίας του image καθώς και το deploy του docker-compose στο swarm. |
|||
|
|||
To Makefile περιέχει τις εντολές: |
|||
[source, sh] |
|||
---- |
|||
echo -e "\e[31mBuilding our nginx image!" |
|||
sleep 2 |
|||
echo -e "\e[39m" |
|||
docker build -f Dockerfile -t anginx . |
|||
echo -e "\e[31mDeploying service" |
|||
sleep 2 |
|||
echo -e "\e[39m" |
|||
docker stack deploy -c docker-compose.yml wordpress |
|||
---- |
|||
|
|||
Στη συνέχεια εκτελούμε την εντολή [underline]#chmod +x Makefile# ώστε να δώσουμε τα απραίτητα δικαιώματα στο αρχείο. |
|||
|
|||
Για να το εκτελέσουμε τρέχουμε το ./Makefile |
|||
|
|||
[TIP] |
|||
O manager ελέγχει ότι όλες οι υπηρεσίες τρέχουν σωστά με την εντολή [underline]#docker service ls# |

Για την εκτέλεση της εργαστηριακής άσκησης χρησιμοποιήσαμε τις υπηρεσίες του https://cyclades.okeanos-knossos.grnet.gr[~okeanos] |
|||
|
|||
Πιο συγκεκριμένα, χρησιμοποιήσαμε ένα VM με τα ακόλουθα χαρακτηριστικά |

== Docker Swarm Initialization |
|||
:nofooter: |
|||
Προκειμένου να δημιουργήσουμε το σμήνος (swarm) ο manager έτρεξε την εντολή |
|||
|
|||
[source, console] |
|||
---- |
|||
docker swarm init --advertise-addr 83.212.77.39 |
|||
---- |
|||
|
|||
Οι workers για να συνδεθούν στο _swarm_ (σμήνος) πρέπει να εκτελέσουν |
|||
[source, console] |
|||
---- |
|||
docker swarm join --token SWMTKN-1-433emh74ij7y4loql5z5js9t7ptxkfdgwwsdzq18p3ag7uxswt-9ah0x5cwf6xnl1djgyet0x si 83.212.77.39:2377 |
|||
---- |
|||
|
|||
[TIP] |
|||
Για να εμφανιστεί το join token ο manager τρέχει την εντολή |
|||
|
|||
[source, console] |
|||
---- |
|||
docker swarm join-token worker |
|||
---- |
|||
|
|||
== Working Directory |
|||
|
|||
Στη συνέχεια δημιουργούμε το working directory μας με την εντολή |
|||
|
|||
[source, console] |
|||
---- |
|||
mkdir docker |
|||
---- |
|||
|
|||
[TIP] |
|||
Αν κάνουμε _pwd_ θα δούμε ότι βρισκόμαστε στο directory /home/user/docker |
|||
|
|||
Όλοι οι χρήστες θα πρέπει να έχουν στον συγκεκριμένο φάκελο τα αρχεία nginx.conf & cert.pem & key.pem |
|||
|
|||
---- |
|||
|_ home |
|||
|_ user |
|||
|_ docker |
|||
|_ nginx.conf |
|||
|_ cert.pem |
|||
|_ key.pem |

== Τεχνολογίες |
|||
|
|||
Για την υλοποίηση της εργασίας χρησιμοποιήθηκε η τεχνολογία *Docker* το οποίο εικονικοποιεί σε επίπεδο λειτουργικού συστήματος. |
|||
|
|||
[source, console] |
|||
---- |
|||
sudo apt-get update |
|||
sudo apt install docker.io |
|||
sudo systemctl start docker |
|||
sudo systemctl enable docker |
|||
---- |
|||
|
|||
[TIP] |
|||
Για να ελέγξουμε ότι η υπηρεσία του *Docker* λειτουργεί εκτελούμε την εντολή |
|||
|
|||
[source, console] |
|||
---- |
|||
docker --version |
|||
---- |
|||
|
|||
== Εκτέλεση Εργασίας |
|||
|
|||
Αρχικά, δημιουργούμε το δικό μας image για τον *nginx* ανάλογα με τις ανάγκες της υπηρεσίας μας. |
|||
|
|||
Το αποθηκεύουμε σε ένα αρχείο ονομάζοντας το [underline]#Dockerfile# |
|||
|
|||
Επόμενο βήμα είναι η εκτέλεση της παρακάτω εντολής για τη δημιουργία του image |
|||
|
|||
[source, console] |
|||
---- |
|||
docker build -f Dockerfile -t anginx . |
|||
---- |
|||
|
|||
[NOTE] |
|||
==== |
|||
Οptions: |
|||
|
|||
* -f προσδιορίζει το αρχείο για το build |
|||
* -t tag (το όνομα του image) |
|||
* "." είναι το current directory |
|||
==== |
|||
|
|||
Όλα τα services τα οποία θα τρέξουν στην εργασία μας βρίσκονται στο αρχείο [underline]#docker-compose.yml# |
|||
