wget https:\/\/download.docker.com\/linux\/centos\/docker-ce.repo -O \/etc\/yum.repos.d\/docker-ce.repo<\/code><\/pre>\n\n\n\n
Aquest comandament descarrega l’arxiu de configuraci\u00f3 del repositori de Docker i el guarda a la ubicaci\u00f3 espec\u00edfica \/etc\/yum.repos.d\/docker-ce.repo<\/code>. Aquest repositori s’utilitza per instal\u00b7lar Docker en sistemes basats en CentOS.<\/p>\n\n\n\n

Desinstal\u00b7lar Docker i els seus components<\/p>\n\n\n\n
dnf remove -y docker docker-client docker-client-latest docker-common docker-latest docker-latest-logrotate docker-logrotate docker-engine<\/code><\/pre>\n\n\n\n
Aquest comandament utilitza DNF per desinstal\u00b7lar Docker i els seus components en un sistema basat en Red Hat o Fedora. L’opci\u00f3 -y<\/code> s’utilitza per confirmar autom\u00e0ticament qualsevol pregunta de desinstal\u00b7laci\u00f3.<\/p>\n\n\n\n

dnf install -y docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin<\/code><\/pre>\n\n\n\n
Aquest comandament instal\u00b7la Docker i els seus components al sistema. Aqu\u00ed hi ha una breu descripci\u00f3 dels paquets instal\u00b7lats:<\/p>\n\n\n\n
    \n
  • docker-ce<\/code>: La versi\u00f3 de la comunitat de Docker.<\/li>\n\n\n\n
  • docker-ce-cli<\/code>: Interf\u00edcie de l\u00ednia de comandes per a Docker.<\/li>\n\n\n\n
  • containerd.io<\/code>: Motor de contenidors per a Docker.<\/li>\n\n\n\n
  • docker-buildx-plugin<\/code>: Connector de Docker per a la construcci\u00f3 multiplataforma.<\/li>\n\n\n\n
  • docker-compose-plugin<\/code>: Connector de Docker per a la gesti\u00f3 de m\u00faltiples contenidors.<\/li>\n<\/ul>\n\n\n\n
    <\/p>\n\n\n\n
    Configurar i habilitar Docker<\/p>\n\n\n\n
    systemctl enable docker && systemctl start docker<\/code><\/pre>\n\n\n\n
    Aquests comandaments configuren Docker com un servei del sistema, assegurant-se que s’inici\u00ef autom\u00e0ticament durant l’arrencada del sistema i despr\u00e9s l’inicien.<\/p>\n\n\n\n

    Obtenir l’\u00faltima versi\u00f3 de Docker Compose<\/p>\n\n\n\n
    vLastVersion=$(curl -s \"https:\/\/api.github.com\/repos\/docker\/compose\/releases\/latest\" | jq -r .tag_name)<\/code><\/pre>\n\n\n\n
    Aquest comandament utilitza cURL i jq per obtenir l’\u00faltima versi\u00f3 de Docker Compose des de l’API de GitHub i l’emmagatzema a la variable vLastVersion<\/code>.<\/p>\n\n\n\n
    <\/p>\n\n\n\n
    Descarregar i instal\u00b7lar Docker Compose<\/p>\n\n\n\n
    curl -L \"https:\/\/github.com\/docker\/compose\/releases\/download\/${vLastVersion}\/docker-compose-$(uname -s)-$(uname -m)\" -o \/tmp\/docker-compose && \\\ncp \/tmp\/docker-compose \/usr\/local\/bin\/docker-compose && \\\nchmod +x \/usr\/local\/bin\/docker-compose && \\\nln -s \/usr\/local\/bin\/docker-compose \/usr\/bin\/docker-compose<\/code><\/pre>\n\n\n\n
    Aquests comandaments descarreguen la versi\u00f3 espec\u00edfica de Docker Compose, la copien al directori \/usr\/local\/bin\/<\/code>, li atorguen permisos d’execuci\u00f3, i creen un enlla\u00e7 simb\u00f2lic a \/usr\/bin\/<\/code> per facilitar-ne l’acc\u00e9s. Aix\u00f2 permet executar Docker Compose des de qualsevol ubicaci\u00f3 al sistema.<\/p>\n\n\n\n
    <\/p>\n\n\n\n
    Afegir l’usuari al grup Docker<\/p>\n\n\n\n
    usermod -aG docker usuari<\/code><\/code><\/pre>\n\n\n\n
    Aquest comandament afegeix l’usuari “usuari” al grup “docker”, permetent-li executar comandes Docker sense necessitat de privilegis de root.<\/p>\n","protected":false},"excerpt":{"rendered":"
