Ka matapakihia e tenei tuhinga pehea te mahi , a ka whai waahi ano hoki mo o raatau hononga ki a Docker.
Mo nga raruraru noa ki a Docker me o raatau otinga , i tenei ra ka whakaahua poto ahau i te whakatinanatanga mai i Kata Containers. Ko Kata Containers he wa whakahaere ipu haumaru i runga i nga miihini mariko mama. Ko te mahi ki a raatau he rite tonu ki etahi atu ipu, engari i tua atu he waahanga pono ake ma te whakamahi i te hangarau mariko taputapu. I timata te kaupapa i te tau 2017, i te wa i oti ai te hapori o taua ingoa te whakakotahitanga o nga whakaaro pai mai i te Intel Clear Containers me Hyper.sh RunV, i muri mai ka haere tonu nga mahi ki te tautoko mo nga momo hoahoanga, tae atu ki te AMD64, ARM, IBM p- me z -raupapa. I tua atu, kei te tautokohia nga mahi i roto i te hypervisors QEMU, Firecracker, me te whakauru ano ki nga ipu. Kei te waatea te waehere i i raro i te raihana MIT.
Nga waahanga matua
- Ma te mahi tahi me te kaupapa motuhake, na reira ka whakarato i te whatunga, te mahara me te wehenga I / O, ka taea te kaha ki te whakamahi i te wehenga taputapu i runga i nga toronga mariko.
- Tautoko mo nga paerewa ahumahi tae atu ki te OCI (whakaahua ipu), Kubernetes CRI
- He rite tonu te mahi o nga ipu Linux auau, kua piki ake te noho wehe me te kore e eke ki runga ake o nga mahi o nga VM auau
- Whakamutua te hiahia ki te whakahaere ipu i roto i nga miihini mariko tino pai, ko nga atanga whanui ka ngawari te whakauru me te whakarewatanga
tāutanga
He Ko nga whiringa whakaurunga, ka whakaaro ahau ki te whakauru mai i nga putunga, i runga i te punaha whakahaere Centos 7.
nui: Ko nga mahi a Kata Containers e tautokohia ana i runga i nga taputapu anake, kaore e mahi tonu te tuku whakamua mariko me tautoko sse4.1 mai i te pūtukatuka.
He ngawari noa te whakauru i nga Ipu Kata:
Whakauruhia nga taputapu mo te mahi me nga putunga:
# yum -y install yum-utilsMonohia a Selinux (he tika ake te whirihora, engari mo te ngawari ka whakakorehia e au):
# setenforce 0
# sed -i 's/^SELINUX=enforcing$/SELINUX=permissive/' /etc/selinux/configKa hono tatou i te putunga me te mahi i te whakaurunga
# source /etc/os-release
# ARCH=$(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-shimwhakatikatikanga
Ka whakarite ahau ki te mahi me te docker, he angamaheni tana whakaurunga, kaore au e whakamaarama atu:
# 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 369ce74a3cKa huri tatou ki daemon.json:
# cat <<EOF > /etc/docker/daemon.json
{
"default-runtime": "kata-runtime",
"runtimes": {
"kata-runtime": {
"path": "/usr/bin/kata-runtime"
}
}
}
EOFTīmata anō te kaitautoko:
# service docker restartWhakamātau Mahi
Mena ka timata koe i te ipu i mua i te whakaara ano i te docker, ka kite koe ka tukuna e uname te putanga o te kernel e rere ana i runga i te punaha matua:
# docker run busybox uname -a

# docker run busybox uname -a

kitenga
Ahakoa te mea e rima ki te tekau nga wa roa te roa o aua ipu ki te tiimata (te wa whakahaere mo nga whakahau rite ina whakamahi containerd he iti iho i te hautoru o te hekona), ka tere tonu te mahi mena ka tangohia e tatou te wa tiimata (kei reira he tauira i runga ake nei, ka mahia nga whakahau i roto i te toru hēkona toharite). Ana, ko nga hua o te whakamatautau tere o te PTM me te RAM e whakaatu ana i nga hua rite tonu, kaore e taea te koa, ina koa na te mea ka tukuna he wehenga ma te whakamahi i tetahi momo whakahaere pai penei i te kvm.
Panui
He arotake te tuhinga, engari ka whai waahi koe ki te rongo i te waa whakahaere rereke. He maha nga waahanga tono kaore i te kapi, hei tauira, ko te waahi e whakaatu ana i te kaha ki te whakahaere i nga Kubernetes ki runga ake o Kata Containers. I tua atu, ka taea hoki e koe te whakahaere i nga raupapa whakamatautau e arotahi ana ki te rapu raruraru haumarutanga, te whakarite here, me etahi atu mea whakamere.
Ka tono ahau ki te hunga katoa kua panui me te whakahoki ano i konei kia uru mai ki te rangahau, ko wai ka whakawhirinaki ki nga whakaputanga a muri ake nei mo tenei kaupapa.
Ko nga kaiwhakamahi kua rehita anake ka uru ki te rangahau. tēnā.
Me whakaputa tonu au i nga tuhinga mo Kata Containers?
