Muchidimbu kutarisisa uye kuseta kweKata Containers

Muchidimbu kutarisisa uye kuseta kweKata Containers
Nyaya ino ichakurukura kuti inoshanda sei Kata Containers, uye kuchave zvakare nechikamu chinoshanda nekubatana kwavo kuDocker.

Nezve matambudziko akajairika neDocker uye mhinduro dzadzo dzatove zvakanyorwa, nhasi ini ndichatsanangura muchidimbu kushandiswa kubva kuKata Containers. Kata Containers yakachengeteka mudziyo runtime yakavakirwa pane lightweight virtual machines. Kushanda navo kwakafanana nemamwe midziyo, asi nekuwedzera kune yakavimbika yekuzvimiririra uchishandisa hardware virtualization tekinoroji. Iyo purojekiti yakatanga muna 2017, apo nharaunda yezita rimwe chete yakapedzisa kubatanidzwa kweakanakisa mazano kubva kuIntel Clear Containers neHyper.sh RunV, mushure mezvo basa rakaenderera pakutsigira kwezvivakwa zvakasiyana siyana, kusanganisira AMD64, ARM, IBM p- uye z. -series. Pamusoro pezvo, basa rinotsigirwa mukati me hypervisors QEMU, Firecracker, uye kune zvakare kubatanidzwa nemukati. Iyo kodhi inowanikwa pa GitHub pasi peMIT rezinesi.

Zvinhu zvakakosha

  • Kushanda neyakaparadzana musimboti, nekudaro ichipa network, ndangariro uye ini / O kuparadzaniswa, zvinokwanisika kumanikidza kushandiswa kwehardware yekuzviparadzanisa nevamwe zvichibva pane virtualization extensions.
  • Tsigiro yezviyero zveindasitiri zvinosanganisira OCI (container fomati), Kubernetes CRI
  • Kuenderana kwekuita kweakajairwa Linux midziyo, yakawedzera kuzviparadzanisa pasina kuita pamusoro peiyo yenguva dzose maVM
  • Bvisa kudiwa kwekumhanyisa midziyo mukati memichina yakazara-yakazara chaiyo, generic interfaces inorerutsa kusanganisa uye kutanga.

Kuiswa

kune mijenya yekuisa sarudzo, ini ndichafunga kuisa kubva kumatura, zvichibva paCentos 7 system yekushandisa.
kosha: Kata Containers basa rinotsigirwa chete pane Hardware, virtualization yekuendesa mberi haishande nguva dzose, zvakare vanoda sse4.1 rutsigiro kubva kune processor.

Kuisa Kata Containers kuri nyore:

Isa zvishandiso zvekushanda nemarepositories:

# yum -y install yum-utils

Dzima Selinux (yakanyanya kurongeka kugadzirisa, asi kuti zvive nyore ndinodzima):

# setenforce 0
# sed -i 's/^SELINUX=enforcing$/SELINUX=permissive/' /etc/selinux/config

Isu tinobatanidza repository uye tinoita kuiswa

# source /etc/os-release
# ARCH=$(arch)
# BRANCH="${BRANCH:-stable-1.10}"
# yum-config-manager --add-repo "http://download.opensuse.org/repositories/home:/katacontainers:/releases:/${ARCH}:/${BRANCH}/CentOS_${VERSION_ID}/home:katacontainers:releases:${ARCH}:${BRANCH}.repo"
# yum -y install kata-runtime kata-proxy kata-shim

kuchinja

Ini ndichamisikidza kushanda nedocker, kuisirwa kwayo kwakajairwa, ini handisi kuzoitsanangura zvakadzama:

# rpm -qa | grep docker
docker-ce-cli-19.03.6-3.el7.x86_64
docker-ce-19.03.6-3.el7.x86_64
# docker -v
Docker version 19.03.6, build 369ce74a3c

Isu tinoita shanduko kune daemon.json:

# cat <<EOF > /etc/docker/daemon.json
{
  "default-runtime": "kata-runtime",
  "runtimes": {
    "kata-runtime": {
      "path": "/usr/bin/kata-runtime"
    }
  }
}
EOF

Tangazve docker:

# service docker restart

Rinoshanda cheki

Kana iwe ukatanga mudziyo usati watangazve docker, unogona kuona kuti uname ichapa iyo vhezheni yekernel inomhanya pane huru system:

# docker run busybox uname -a

Mushure mekutangazve, iyo kernel vhezheni inotaridzika seizvi:

# docker run busybox uname -a
