Установка Docker+DockerCompose+KubeCtl+Helm

Установка Docker CE

# apt-get update
# apt-get install ca-certificates curl
# install -m 0755 -d /etc/apt/keyrings
# curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc
# chmod a+r /etc/apt/keyrings/docker.asc
# echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/ubuntu \
  $(. /etc/os-release && echo "${UBUNTU_CODENAME:-$VERSION_CODENAME}") stable" | \
  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
# apt-get update
# apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

Установка Docker Compose

# curl -L https://github.com/docker/compose/releases/download/v2.33.1/docker-compose-linux-x86_64 -o /usr/local/bin/docker-compose
# chmod +x /usr/local/bin/docker-compose
# ln -s /usr/local/bin/docker-compose /usr/local/bin/dc

Авто-дополнение команд при помощи TAB

Для Docker автодополнение автоматом, а для Docker Compose только для версии 1.26.2, но там по командам ничего не поменялось.

# curl -L https://raw.githubusercontent.com/docker/compose/1.26.2/contrib/completion/bash/docker-compose > /etc/bash_completion.d/docker-compose

Добавляем пользователя в группу Docker

# usermod -aG docker chernousov
