TL;DR: Praevisus dux ad compages comparandas pro applicationibus currit in vasis. Facultates Docker aliaeque huiusmodi systemata considerentur.
Historia parva ubi omnia
historia
Prima nota methodi applicationis segregandi chroot est. Systema vocationis eiusdem nominis efficit ut radix directorii mutetur - ita ut programma quod appellatur ei accessum habeat solum ad lima in illo presul. Sed si progressio privilegiorum radicitus interne datur, potentia "effugere" chroo potest et accedere ad principale systematis operandi. Etiam, praeter directorium radicis mutandum, aliae facultates (RAM, processor), accessus reticularis non limitantur.
Methodus sequens est systema operandi plenum intra receptaculum currere, mechanismis nuclei systematis operandi utens. Haec methodus nomina diversa in diversis systematibus operandi habet, sed essentia eadem est: plura systemata operandi independentia currere, quorum unumquodque eundem nucleum ac systema operandi principale currit. Hoc includit carceres FreeBSD, zonas Solaris, OpenVZ, et LXC pro... LinuxIsolatio non solum spatio disci, sed etiam aliis opibus praebetur; praesertim, unumquodque receptaculum limites temporis CPU, RAM, et latitudinis retialis habere potest. Comparatum cum chroot, exire ex receptaculo difficilius est, cum superusor in receptaculo tantum ad interna receptaculi accessum habeat. Attamen, propter necessitatem systematis operandi intra receptaculum renovandi et usum versionum nuclei vetustiorum (pertinens ad... Linux(et minore modo FreeBSD) probabilitas non nulla est "perrumpendi" systema isolationis nuclei et aditum ad systema operandi principale adipiscendi.
Potius quam plenae armaturae systematis operandi in vase (cum systemate initializatione, involucro procuratori, etc.) deducendis statim applicationes deducere potes, summa res est applicationes tali opportunitate praebere (praesentibus bibliothecis necessariis. et alia lima). Haec idea pro fundamento applicationis virtualisationis continentis inserviebat, cuius repraesentativum praestantissimum et notissimum est Docker. Comparati ad systemata priora, machinationes solitariae flexibiles, quae constructae-in subsidiis virtualis reticulis inter continentia et applicationem status sequi intra continentem, consecuta sunt in facultate aedificandi unum ambitum cohaerentem e magno numero ministrantium physicarum ad currentium vasorum. sine manuali subsidiorum necessitate procuratio.
Docker
Docker est programmatura ad applicationes in receptacula collocandas notissimum. Lingua Go scriptum est et facultates nuclei nativas adhibet. Linux — greges programmatum (cgroups), spatia nominum, facultates, et cetera, necnon systemata fasciculorum Aufs et similia ad spatium disci conservandum.

Architecture
Ante versionem 1.11, Docker ut unum ministerium agebat quod omnes operationes continentium curabat: imagines continentium detrahendas, continentia incipienda, et petitiones API tractandas. A versione 1.11 incipiens, Docker in plures partes inter se agentes divisus est: containerd, quae totum cyclum vitae continentium (assignationem discorum, detractionem imaginum, connexionem retiariam, initium, institutionem, et monitorationem status continentium) curabat, et runC, ambitum executionis continentium in cgroups et aliis notis nuclei fundatum. LinuxIpsum ministerium Docker manet, sed nunc tantum ad petitiones API ad containerd transmissas tractandas inservit.
Installation et configuratione
Meus ventus modus ad instituendum docker machina est machina, quae, praeter directe inaugurari et configurare in remotis servientibus (nubila variis inclusis), efficit ut possibilitas operandi cum fasciculi systematibus remotis servientibus ac etiam varia mandata currere possit.
Attamen, ab anno 2018 proiectum vix elaboratum est, itaque illud instituemus methodo consueta plerisque distributionibus utentes. Linux methodus — repositorium addendo et fasciculos necessarios instituendo.
Haec methodus etiam ad institutionem automated adhibetur, exempli gratia Ansible vel aliis similibus systematibus utens, sed in hoc articulo non considero.
Installatio peragetur die Centos 7, machinam virtualem ut servitorem utar, ad institutionem satis est mandata infra exsequi:
# yum install -y yum-utils
# yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
# yum install docker-ce docker-ce-cli containerd.ioPost institutionem, officium incipere debes et in startup pone:
# systemctl enable docker
# systemctl start docker
# firewall-cmd --zone=public --add-port=2377/tcp --permanentAccedit, catervam docularium creare potes, cuius usores sine sudo operari possunt, colligationem erige, aditum ad API ab extra da, nec obliviscere pressius parietem configurare (omnia quae non licet. prohibetur in exemplis supra et infra - hoc pro simplici et perspicuitate omisi), sed hic planius non ingrediar.
alius features
Praeter supra memoratam machinam technologiam subcriptio etiam est subcriptio, instrumentum ad imagines reponendas pro vasis, ac in vasis componendis, instrumentum ad automandum instruere applicationes in vasis, fasciculi YAML ad vasa construenda et configuranda. aliaeque res affines (exempli gratia retiacula, systemata fasciculi persistentes pro reposita notitia).
Ponere etiam potest vectores pro CICD. Alia notatio interesting in botro modo laborat, qui modus examinandi sic dictus (ante versionem 1.12 notus erat examen docker), quod permittit te unum infrastructuram convenire a pluribus servientibus pro vasis currentibus. Subsidium virtualis retis super omnibus servientibus est, constructum-in librario oneris, ac subsidium secretorum pro vasis.
YAML fasciculi ex docker componunt, cum minoribus modificationibus, pro talibus racemis adhiberi possunt, omnino automando sustentationem racemis parvis et mediocribus ad varios usus. Kubernetes pro magnis racemis potior est quia sumptibus sustentationis modus examinandi illos Kubernetes excedere potest. Praeter runC, instituere potes, exempli gratia, continens supplicium environment
Operantes cum Docker
Post institutionem et configurationem, botrum convenire conabimur in quo explicabimus GitLab et Docker Subcriptio pro quadrigis evolutionis. Utar tribus machinis virtualibus servientibus, in quibus dispersas FS GlusterFS insuper explicabo, eo utar in repositione volumina, verbi gratia, ut in scriptione technicae versionis vitiosum tolerantem concurram. Clavis partium ad currendum: Docker Subcriptio, Postgresql, Redis, GitLab cum auxilio GitLab Cursor super examen. Postgresql cum pampineis immittet nobis , ideo non opus est ut GlusterFS ad notitias Postgresql reponendas. Reliquae notitiae criticae in GlusterFS reponendae sunt.
GlusterFS omnibus servientibus explicandis (nodi1, node2, node3) explicandis, fasciculos instituere debes, firewall da, et necessaria directoria crea;
# yum -y install centos-release-gluster7
# yum -y install glusterfs-server
# systemctl enable glusterd
# systemctl start glusterd
# firewall-cmd --add-service=glusterfs --permanent
# firewall-cmd --reload
# mkdir -p /srv/gluster
# mkdir -p /srv/docker
# echo "$(hostname):/docker /srv/docker glusterfs defaults,_netdev 0 0" >> /etc/fstabPost institutionem, opus figurandi GlusterFS ab una nodo protrahendum est, exempli gratia nodi1:
# gluster peer probe node2
# gluster peer probe node3
# gluster volume create docker replica 3 node1:/srv/gluster node2:/srv/gluster node3:/srv/gluster force
# gluster volume start dockerTunc opus est ut inde volumen conscendas (quod mandatum est omnibus servientibus exsecutioni mandandum);
# mount /srv/dockerExamen modum configuratur in uno ex ministris, qui erit Dux, reliqui iungendi botrum debebunt, ut effectus mandati servientis exsequi debebit exscribere et in alios exscribere.
Botrus initialis paro, praeceptum in node1 curro;
# docker swarm init
Swarm initialized: current node (a5jpfrh5uvo7svzz1ajduokyq) is now a manager.
To add a worker to this swarm, run the following command:
docker swarm join --token SWMTKN-1-0c5mf7mvzc7o7vjk0wngno2dy70xs95tovfxbv4tqt9280toku-863hyosdlzvd76trfptd4xnzd xx.xx.xx.xx:2377
To add a manager to this swarm, run 'docker swarm join-token manager' and follow the instructions.
# docker swarm join-token managerEx secundo mandato nos imitari et illum in node2 et nodi3 facere;
# docker swarm join --token SWMTKN-x-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx-xxxxxxxxx xx.xx.xx.xx:2377
This node joined a swarm as a manager.Hoc loco, praevia ministrantium conformatio, ad officia instituenda procedamus, mandata exsecutioni mandanda node1, nisi aliud constet.
Primum retiacula pro vasis crearemus:
# docker network create --driver=overlay etcd
# docker network create --driver=overlay pgsql
# docker network create --driver=overlay redis
# docker network create --driver=overlay traefik
# docker network create --driver=overlay gitlabTunc servientibus notamus, necesse est ut servientibus aliqua officia ligare debeamus;
# docker node update --label-add nodename=node1 node1
# docker node update --label-add nodename=node2 node2
# docker node update --label-add nodename=node3 node3Deinde directoria creamus ad notitias etcd reponendas, KV repositiones, quae ad Traefik et Stolon opus sunt. Similia cum Postgresql, haec vasa servientibus ligata erunt, hoc mandatum in omnibus servientibus curritur:

podman
Aliud satis notum machinam ad decurrentem vascula per siliquas (siliquas, catervas vasorum in unum explicant). Dissimilis Docker, non requirit aliquod officium ut vasa currendi, omne opus per bibliothecam libpod. Etiam in Go scriptum, postulat runtime OCI compatible ut vasis currendi, ut runC.
Podman laborans plerumque simile est illius pro Docker, adeo ut hoc facere possis (ut a multis dictum est, qui id experti sunt, auctori huius articuli);
$ alias docker=podmanac pergere potes. In genere, res cum Podman valde iucunda est, quia si primae versiones Kubernetes cum Docker laboraverunt, tunc circa 2015, post normas mundi continentium (OCI - Aperi Continentis Initiativum) et divisio Docker in continentem et runC; jocus Docker ad currendum in Kubernetes evolvens: CRI-O. Podman hac in re jocus est ad Docker, in principiis Kubernetes constructum, inter continentes coagmentatum, sed praecipuum propositi propositum est continentibus Docker-style sine additis officiis deducendi. Ex apertis rationibus nullus est examinatio modus, quia clare tincidunt dicunt, si botri opus est, accipe Kubernetes.
Occasum
Ad institutionem in Centos 7, repositorium Extras tantum activa et deinde omnia hoc mandato instala:
# yum -y install podmanalius features
Podman potest unitates generare pro systemd, ita problema solvendo vasis incipiendi post reboot servitoris. Accedit systemd quod recte operari declaratur sicut pid 1 in vase. Instrumentum constructum separatum est pro vasis aedificandis, sunt instrumenta tertia-partium - analoga docker-compositi, quae etiam genera conformationis imaginum compatitur cum Kubernetes, ita transitus a Podman ad Kubernetes quam maxime facilior est.
Opus Podman
Cum modus examinandi non sit (si botrus ad Kubernetes mutandae putemur), in vasis separatis colligemus.
Instrue podman-componere:
# yum -y install python3-pip
# pip3 install podman-composeConfigurationis lima inde pro podman paulo diversa est, ut exempli gratia singula volumina sectionem directe ad sectionem cum officiis movere debebamus.

WantedBy=multi-user.targetInfeliciter, sine vasis deducendis, unitas generata ad systema nihil aliud agit (exempli gratia, vascula vetera redigit cum talis servitus sistat), sic debebis scribere talia teipsum.
In principio, Podman satis est experiri quae vasa sunt, antiquas figurationes pro componendis sculpendis transferre, et ad Kubernetes movere, si botro indiges, aut faciliorem utendo ad Docker.
rkt
project ante sex menses ob hoc quod RedHat emit, accuratius in eo non habito. Super, optimam impressionem reliquit, sed Docker et praesertim Podman comparatus, coniunctio similis est. Distributio CoreOS super rkt aedificata fuit (quamvis Docker primitus habuerat), sed hoc etiam in subsidiis post RedHat emptionis finem fecit.
Plush
magis cuius auctor modo vasa construere et currere voluit. Ex documentis et codice iudicans, auctor signa non secutus est, sed solum exsecutionem suam scribere constituit, quae in principio fecit.
Inventiones
Res cum Kubernetis admodum iucunda est: ex altera parte, cum Docker botrum (examinis modo), cum quo etiam productum ambitus clientium currere potes, hoc maxime verum est pro parvis iugis (3-5 homines); aut cum parvo altiore onere, aut non desiderio intelligendi ambages statuendi Kubernetes, pro magnis oneribus inclusis.
Podman plenam convenientiam non praebet, sed unum magnum commodum habet - convenientiam cum Kubernetes, additis instrumentis (aedificiis et aliis). Ideo aggrediar electionem instrumenti operis hoc modo: pro parvis iugis, vel cum praescriptione limitata - Docker (cum examinis modo possibili), ad explicandum me in personali locali - Podman comitum et pro omnibus aliis. — Kubernetes.
Non certus sum an res cum Docker in futuro non mutetur, nam illi sunt pionerii, et gradatim paulatim ad normam perveniunt, sed Podman, omnibus suis defectibus non obstantibus (solum in... operans...) Linux, nullae actiones coacervationis, congregationis, aliaeque a solutionibus tertiarum partium peraguntur) futurum clarius est, ergo omnes invito ut de his inventis in commentariis disserant.
PS Die 3 Augusti deducimus "", ubi plura de opere suo cognoscere potes. Omnia instrumenta eius resolvemus: ab abstractis fundamentalibus ad parametris retis, nuances operandi cum variis systematibus operandis et linguis programmandis. Nota fies cum technicae artis et intellege ubi et quam optime utatur Docker. Nos quoque casuum praxim participemus.
