lxc exec jupyterlab -- cp /etc/skel/.bashrc /root/.bashrc
lxc exec jupyterlab -- cp /etc/skel/.dir_colors /root/.dir_colors

Alpine Linux inoisa system shell yevashandisi /bin/sh, tichaitsiva nayo root mushandisi muBash:

lxc exec jupyterlab -- usermod --shell=/bin/bash root

kuti root mushandisi anga asiri asina password, anofanirwa kuseta password. Iwo unotevera murairo uchagadzira uye kuseta nyowani isina kurongeka password kwaari, iyo yauchaona pane iyo console skrini mushure mekuita kwayo:

lxc exec jupyterlab -- /bin/bash -c "PASSWD=$(head /dev/urandom | tr -dc A-Za-z0-9 | head -c 12); echo "root:$PASSWD" | chpasswd && echo "New Password: $PASSWD""

New Password: sFiXEvBswuWA

Zvakare, ngatigadzirei mushandisi mutsva system - jupyter izvo zvatichagadzirisa gare gare jupyter lab:

lxc exec jupyterlab -- useradd --create-home --shell=/bin/bash jupyter

Ngatigadzire uye tiise password yayo:

lxc exec jupyterlab -- groupmems --group sudo --add jupyter

Ngationei kuti mushandisi ndewemapoka api jupyter:

lxc exec jupyterlab -- id -Gn jupyter

jupyter sudo

Zvese zvakanaka, ngatienderere mberi.

Bvumira vashandisi vese vari nhengo dzeboka sudo shandisa command sudo. Kuti uite izvi, shandisa script inotevera, kupi sed uncomments parameter mutsara mufaira rekugadzirisa /etc/sudoers:

lxc exec jupyterlab -- /bin/bash -c "sed --in-place -e '/^#[ t]*%sudo[ t]*ALL=(ALL)[ t]*ALL$/ s/^[# ]*//' /etc/sudoers"

Kuisa uye kugadzirisa JupyterLab ^

jupyter lab iPython application, saka tinofanira kutanga taisa muturikiri uyu. Zvakare, jupyter lab isu tichaisa tichishandisa iyo Python package maneja pip, uye kwete iyo system imwe, nekuti inogona kunge yakare musystem repository uye nekudaro, isu tinofanirwa kugadzirisa nemaoko kutsamira kwairi nekuisa anotevera mapakeji - python3 python3-dev gcc libc-dev zeromq-dev:

lxc exec jupyterlab -- apk add python3 python3-dev gcc libc-dev zeromq-dev

Ngatigadzirise python modules uye package maneja pip kune yazvino vhezheni:

lxc exec jupyterlab -- python3 -m pip install --upgrade pip setuptools wheel

Install jupyter lab kuburikidza nePackage Manager pip:

lxc exec jupyterlab -- python3 -m pip install jupyterlab

Kubva pakuwedzerwa mukati jupyter lab ari kuyedza uye haana kutumirwa zviri pamutemo nejupyterlab package, saka isu tinofanirwa kuiisa nekuigadzirisa nemaoko.

Ngatiisei NodeJS uye maneja wepakeji yayo - NPM, kubvira jupyter lab inoashandisa pakuwedzera kwayo:

lxc exec jupyterlab -- apk add nodejs npm

Kuwedzera kune jupyter lab izvo zvatichaisa zvakashanda, zvinoda kuiswa mudhairekitori remushandisi sezvo application ichavhurwa kubva kumushandisi jupyter. Dambudziko nderekuti hapana parameter mukuraira kwekutanga iyo inogona kupfuudzwa kune dhairekitori; iyo application inongogamuchira nharaunda inosiyana uye saka tinofanira kuitsanangura. Kuti tiite izvi, isu tichanyora iyo variable export command JUPYTERLAB_DIR munharaunda yemushandisi jupyter, kufaira .bashrciyo inoitwa pese apo mushandisi anopinda:

lxc exec jupyterlab -- su -l jupyter -c "echo -e "nexport JUPYTERLAB_DIR=$HOME/.local/share/jupyter/lab" >> .bashrc"

Murairo unotevera uchaisa yakakosha yekuwedzera - yekuwedzera maneja mukati jupyter lab:

lxc exec jupyterlab -- su -l jupyter -c "export JUPYTERLAB_DIR=$HOME/.local/share/jupyter/lab; jupyter labextension install --no-build @jupyter-widgets/jupyterlab-manager"

Iye zvino zvinhu zvose zvakagadzirira kutanga kwekutanga jupyter lab, asi isu tinogona kuisa mashoma anobatsira ekuwedzera:

  • toc -Tafura yeZviri mukati, inogadzira runyorwa rwemisoro muchinyorwa/notibhuku
  • jupyterlab-horizon-theme - UI theme
  • jupyterlab_neon_theme - UI theme
  • jupyterlab-ubu-theme - Imwe zvekare dingindira kubva kumunyori chinyorwa ichi :) Asi mune iyi kesi, kuiswa kubva kuGitHub repository kucharatidzwa

Saka, mhanyisa mirairo inotevera sequentially kuti uise aya ekuwedzera:

lxc exec jupyterlab -- su -l jupyter -c "export JUPYTERLAB_DIR=$HOME/.local/share/jupyter/lab; jupyter labextension install --no-build @jupyterlab/toc @mohirio/jupyterlab-horizon-theme @yeebc/jupyterlab_neon_theme"

lxc exec jupyterlab -- su -l jupyter -c "rm -r jupyterlab-ubu-theme-master"

Mushure mekuisa ekuwedzera, isu tinofanirwa kuaunganidza, sezvo kare, panguva yekuisa, isu takatsanangura kiyi --no-build kuchengetedza nguva. Iye zvino isu ticha mhanyisa zvakanyanya nekuvabatanidza pamwechete mune imwe kuenda:

lxc exec jupyterlab -- su -l jupyter -c "export JUPYTERLAB_DIR=$HOME/.local/share/jupyter/lab; jupyter lab build"

Zvino mhanya iyo inotevera mirairo miviri kuti uiite kekutanga jupyter lab. Zvingave zvichiita kuti utange nemurairo mumwe chete, asi munyaya iyi, murairo wekutanga, izvo zvakaoma kuyeuka mupfungwa dzako, zvichayeukwa nebash mumudziyo, uye kwete pamubati, uko kune mirairo yakakwana. kuvanyora munhoroondo :)

Pinda mumudziyo semushandisi jupyter:

lxc exec jupyterlab -- su -l jupyter

Tevere, mhanya jupyter lab nemakiyi uye parameter sezvakaratidzwa:

[jupyter@jupyterlab ~]$ jupyter lab --ip=0.0.0.0 --no-browser

Enda kukero muwebhu browser yako http://10.0.5.5:8888 uye papeji inovhura pinda chiratidzo kuwana iyo iwe yauchaona mune iyo console. Kopa uye unamate pane peji, wobva wadzvanya Login. Mushure mekupinda mukati, enda kumenu yekuwedzera kuruboshwe, sezvakaratidzwa mumufananidzo uri pazasi, kwauchazokurudzirwa, paunenge uchimisa maneja wekuwedzera, kutora njodzi dzekuchengetedza nekuisa mawedzero kubva kune vechitatu mapato ayo iwo murairo. JupyterLab kuvandudzwa haana mhosva:

Kuvhura Jupyter muLXD orbit

Nekudaro, isu tiri kuparadzanisa zvese jupyter lab uye woiisa mumudziyo kuitira kuti yechitatu-bato yekuwedzera inoda uye kushandisa NodeJS haigone kuba data pane dhisiki kunze kweiyo yatinovhura mukati memudziyo. Enda kune ako akavanzika magwaro pane iyo host in /home maitiro kubva mumudziyo haafanire kubudirira, uye kana vakadaro, saka iwe unofanirwa kuve neropafadzo pamafaira pane iyo host system, sezvo isu tichimhanyisa mudziyo mukati. unprivileged mode. Zvichienderana neruzivo urwu, unogona kuongorora njodzi yekusanganisira mawedzero mukati jupyter lab.

Yakagadzirwa IPython zvinyorwa (mapeji mukati jupyter lab) zvino ichagadzirwa mudhairekitori remusha remushandisi - /home/jupyter, asi zvirongwa zvedu ndezvekutsemura data (gova) pakati pemugamuchiri nemudziyo, saka dzokera kune koni uye mira. jupyter lab nekuita hotkey - CTRL+C uye achipindura y pakukumbira. Wobva wamisa musangano wemushandisi jupyter kuzadza hotkey CTRL+D.

Kugovera data nemugamuchiri ^

Kuti ugovane data nemuiti, unofanirwa kugadzira mudziyo mumudziyo unobvumidza iwe kuti uite izvi uye kuti uite izvi, mhanyisa unotevera kuraira kwatinotsanangura makiyi anotevera:
