Docker Swarm menene kuma yadda ya bambanta da Kubernetes?

Question

Accepted Answer

**Docker Swarm** shine kayan aikin gudanarwa na kwamanda na Docker - wanda ke juya rukuni na masibiti na Docker zuwa wata gida da ke samun himma ta hanyoyin Docker da aka saba. Yana da sauƙi fiye da Kubernetes amma ba shi da ƙarfi sosai; fahimtar dukansu yana taimakon zaɓi ortaya gastun da ya dace.

## Abin da Docker Swarm ke bayarwa

```text
Swarm clusters multiple Docker hosts and orchestrates containers ("services"):
  ✓ Built into Docker — uses familiar Docker CLI/Compose-like syntax (low learning curve)
  ✓ SERVICES with replicas; scheduling across nodes; SELF-HEALING (restart failed tasks)
  ✓ Scaling, ROLLING UPDATES/rollbacks, overlay networking, service discovery, secrets
  ✓ Load balancing (built-in routing mesh)
```

```bash
docker swarm init                              # initialize a swarm (this node = manager)
docker service create --replicas 3 --name web -p 80:80 nginx   # a replicated service
docker service scale web=5                     # scale
docker service update --image nginx:1.25 web   # rolling update
```

## Swarm da Kubernetes

```text
                  Docker Swarm              Kubernetes
Complexity        Simple, easy to learn     Complex, steep learning curve
Setup             Quick (built into Docker) More involved
Power/features    Adequate, fewer features  Very powerful, extensive ecosystem
Scale             Smaller/simpler clusters  Massive scale, complex apps
Ecosystem         Limited                   Huge (the industry standard)
Auto-scaling      Manual/limited            Advanced (HPA, etc.)
Adoption          Declining                 Dominant (de facto standard)
```

## Lokaci da za a yi amfani da wanne

```text
SWARM → simpler needs, small teams, quick setup, when Kubernetes is overkill;
  you value simplicity over features
KUBERNETES → production at scale, complex requirements, rich ecosystem needs,
  industry-standard tooling/skills, advanced features (the dominant choice)
→ The industry has largely consolidated on Kubernetes; Swarm fits simpler cases.
```

## Me ya sa haka ya tabbata

Fahimtar Docker Swarm da yadda ya bambanta da Kubernetes ilimi ne mai mahimmanci ga matakin saniye don **yin saissai na ortayen gudanarwa**, saboda akela yana da amfani ga siyasar gida-gida. **Docker Swarm** yana ba da ortayan gudanarwa na kwamanda (tsammani masibiti, gudanarwa da ayyukan da aka maimaita tare da gyara kanta, ka'ida, sabunta da juyawa, haɗin sadarwa na overlay, da daidaitawa) tare da manufa ta muhimmanci: **ana samun shi a ciki ga Docker kuma yana amfani da aska na Docker da aka saba**, yana ba shi **ƙaramin karattar karatu da mabilis na shiryawa** — yana sa shi zaɓi mai ma'ana lokacin da cikakken ƙirjin Kubernetes ba ya dace.

Fahimtar **bambantaa da Kubernetes** shine ƙimar kasuwa: Swarm yana **sauƙi da fadi sauƙi** amma **tsakani ba shi da ƙarfi tare da karamin ecosystem**, yayin da Kubernetes **ba shi da karfin gida tare da tunkalin karattar karatu** amma **baƙon kima sosai** tare da m̀adaidaita ecosystem, ƙwararrun kukkuna (akai-akai na kuskure, da sauransu), da **riga-kofarar malikan kasua** — daidaita sani na wajibi.

Fahimtar **lokaci da za a yi amfani da wanne** (Swarm don bukatun sauƙi, ƙaramin ƴan gida, da mabisk na shiryawa inda Kubernetes ba ya dace; Kubernetes don aiki a girma, rikitattun bukatun, da hannu zuwa ecosystem na daidaita da ƙwararru) ya nuna **ƙa'idar gida mabur** — sanin da sauƙi kayan aiki sun isa don sauƙi bukatun, yayin da kuma jin cewa kasua ta **takaice sosai dapat Kubernetes** (saboda alamar Swarm tana raguwa kuma ƙwararrun Kubernetes sun samu karɓi fita).

Banantaccen fahimtar nan — sanin Swarm akwai a matsayi-sauƙin zaɓi yayin da kuma sanin iko da karfin Kubernetes — yana hada da saissai na ortayan gudanarwa na gida.

Tun da zaɓin ortayan gudanarwa yana da mahimmanci ga a fuiyen kwamanda da akwai gaske bambantaa tsakani sauƙi (Swarm) da iko/ecosystem (Kubernetes), kuma tun da fahimtar dukansu tana bayyani lokaci kowa ya zo (yayin da kuma sanin iko da karfin Kubernetes na kasua), fahimtar Docker Swarm da bambantawar sa da Kubernetes ilimi ne mai mahimmanci ga matakin saniye don ortayen gudanarwa, nuna sanin kasuar ortayan gudanarwa da hankali don daidaita kayan aiki ga rikitattun gwargwaro da girman halaye.
