🥇Docker Componere: ab progressu ad productionem

Translatio podcasts transcriptio praeparata in antecessum curriculi "Administrator Linux"

Docker Componere est instrumentum mirabile opus faciendi
environment pro ACERVUS in applicatione tua usus est. Non concedit ut definias
unaquaeque pars applicationis tuae, secundum syntaxin claram et simplicem YAML-
files.

Adveniente docker componere v3 Haec YAML files directe adhiberi possunt in environment productio cum operantes cum
botrus Versus Docker.

Sed hoc significat quod eodem tabellario uti potes
processu evolutionis et in ambitu productionis? Aut uti eadem lima for
choragium? Bene, in universum, immo, sed ad hanc functionem necessariam est quae sequuntur:

Interpolatio variabilis: usus environment variabiles aliquot
valores mutandi in unaquaque environment.
Configurationis primi ante: definire secundum facultatem (vel aliquo
aliud sequens) fasciculum docker-componere qui aliquid de mutatione mutabit
primum, et docker componere curabit utrasque tabulas mergendi.

Differentiae inter evolutionis et productionis files

Per progressionem, maxime verisimile vis mutationes in codice reprimendam
realis tempus. Ad hoc faciendum, plerumque codicem cum fonte codice annectitur
continens quod contineat runtime pro applicatione tua. Sed a consequat mauris
Modus hic non convenit.

In productione botrum multis nodis habes, et volumen locale est
relativum ad nodi in quo vas tuum (vel servitium) currit, sic non facis
potes conscendere source code sine operationibus implicatis, quae includit
codice, synchronisation, significationibus, etc.

Sed solemus imaginem creare cum certa versione codicis tui.
Solet notare eam cum tag congruo (semantico uti potes"
versioning vel alia ratio ad arbitrium tuum).

Configurationis Override

Datae differentiae et ut clientelae vestrae in missionibus differant
Patet progressionem et productionem diversis imaginum conformationibus egere.

Docker componere subsidia bus diversis componere files to
ultima configuratione obtinent. Quomodo haec opera in exemplo videri possint;

$ cat docker-compose.yml
version: "3.2"

services:
  whale:
    image: docker/whalesay
    command: ["cowsay", "hello!"]
$ docker-compose up
Creating network "composeconfigs_default" with the default driver
Starting composeconfigs_whale_1
Attaching to composeconfigs_whale_1
whale_1  |  ________
whale_1  | < hello! >
whale_1  |  --------
whale_1  |     
whale_1  |      
whale_1  |       
whale_1  |                     ##        .
whale_1  |               ## ## ##       ==
whale_1  |            ## ## ## ##      ===
whale_1  |        /""""""""""""""""___/ ===
whale_1  |   ~~~ {~~ ~~~~ ~~~ ~~~~ ~~ ~ /  ===- ~~~
whale_1  |        ______ o          __/
whale_1  |                     __/
whale_1  |           __________/
composeconfigs_whale_1 exited with code 0

Sicut dixit, docker componit subsidia multiplicia componit -
fasciculi, hoc tibi permittit ut varias parametris in secunda fasciculo vincas. Exempli gratia:

$ cat docker-compose.second.yml
version: "3.2"
services:
  whale:
    command: ["cowsay", "bye!"]

$ docker-compose -f docker-compose.yml -f docker-compose.second.yml up
Creating composeconfigs_whale_1
Attaching to composeconfigs_whale_1
whale_1  |  ______
whale_1  | < bye! >
whale_1  |  ------
whale_1  |     
whale_1  |      
whale_1  |       
whale_1  |                     ##        .
whale_1  |               ## ## ##       ==
whale_1  |            ## ## ## ##      ===
whale_1  |        /""""""""""""""""___/ ===
whale_1  |   ~~~ {~~ ~~~~ ~~~ ~~~~ ~~ ~ /  ===- ~~~
whale_1  |        ______ o          __/
whale_1  |                     __/
whale_1  |           __________/
composeconfigs_whale_1 exited with code 0

Haec syntaxis non admodum convenit in evolutione, cum mandatum
pluries fieri oportebit.

Feliciter, docker componere automatice specialem tabellam vocatam quaerit
docker-compose.override.yml nolens oboedire values Docker compose.yml,. si
secunda fasciculi secunda nomine, idem eventum accipis, tantum utendo imperio originali;

$ mv docker-compose.second.yml docker-compose.override.yml
$ docker-compose up
Starting composeconfigs_whale_1
Attaching to composeconfigs_whale_1
whale_1  |  ______
whale_1  | < bye! >
whale_1  |  ------
whale_1  |     
whale_1  |      
whale_1  |       
whale_1  |                     ##        .
whale_1  |               ## ## ##       ==
whale_1  |            ## ## ## ##      ===
whale_1  |        /""""""""""""""""___/ ===
whale_1  |   ~~~ {~~ ~~~~ ~~~ ~~~~ ~~ ~ /  ===- ~~~
whale_1  |        ______ o          __/
whale_1  |                     __/
whale_1  |           __________/
composeconfigs_whale_1 exited with code 0

Bene, ut facilius meminisse.

Interpositio variabilium

Configurationis files support interpolatio
variabilium et defaltam fecerit. Id est, potes facere;

services:
  my-service:
    build:
      context: .
    image: private.registry.mine/my-stack/my-service:${MY_SERVICE_VERSION:-latest}
...

Et si feceritis docker-componere constructum (vel dis) sine environment variabilis
$MY_SERVICE_VERSION, De valore utendum est Latestsed si posuistis
valor variabilis ante fabricandi, cum aedificaretur vel propellentibus adhibebitur
ad actis mandare private.registry.mine.

mea principia

Accessiones qui operantur pro me, laboro tibi quoque. sequor haec
simplex praecepta;

Omnes mei acervi ad productionem, progressionem (vel alias ambitus) definiuntur
docker-componere files
Configurationis lima opus est ut omnes ambitus meos, quantum fieri potest, operiat
duplicationem vitare.
Unum praeceptum simplex opus est ad operandum in unaquaque provincia.
Configuratione principalis definitur in tabella Docker compose.yml,.
Environment variables sunt ad definiendam imaginem tags vel alia
variabiles, quae variari possunt a ambitu ad ambitum (sagittarius, integratio;
Fabricatio).
Valores variabilium productionis adhibentur ut valores pro
per defaltam, haec minimizet periculum si acervus in productione sine
posuere consequat varius.
Incipere servitium in ambitu productionis, imperio uti ACERVUS docker explicandam - componere-file docker-compose.yml cum subcriptio-auth my-BIBLIOTHECA-nomen.
Operatio environment incepit per mandatum d-sursum componere Docker.

Intueamur exemplum simplex.

# docker-compose.yml
...
services:
  my-service:
    build:
      context: .
    image: private.registry.mine/my-stack/my-service:${MY_SERVICE_VERSION:-latest}
    environment:
      API_ENDPOINT: ${API_ENDPOINT:-https://production.my-api.com}
...

# docker-compose.override.yml
...
services:
  my-service:
    ports: # This is needed for development!
      - 80:80
    environment:
      API_ENDPOINT: https://devel.my-api.com
    volumes:
      - ./:/project/src
...

Ego uti potest docker-componere (docker-componere)currere ACERVUS in
progressus modus cum fonte codice mounted in /project/src.

Iisdem fasciculis uti possum in productione! Et certe uti
idem file Docker compose.yml, ad choragium. Ad hoc expand to
productio, Modo opus est aedificare imaginem et mittere cum tag praedefinito
CI ad scaenam:

export MY_SERVICE_VERSION=1.2.3
docker-compose -f docker-compose.yml build
docker-compose -f docker-compose.yml push

In productione, hoc potest currere utendo mandato sequenti;

export MY_SERVICE_VERSION=1.2.3
docker stack deploy my-stack --compose-file docker-compose.yml --with-registry-auth

Et si idem in scaena facere vis, tantum debes definire
necesse environment variabiles ad operandum in choragiis environment:

export MY_SERVICE_VERSION=1.2.3
export API_ENDPOINT=http://staging.my-api.com
docker stack deploy my-stack --compose-file docker-compose.yml --with-registry-auth

Quam ob rem duabus diversis fasciculis pharmacopola componendis usi sumus, quae sine
Configurationes duplicatae adhiberi possunt pro quolibet ambitu quam habetis!
