How do I get roscd, rostopic, roscore, rosrun and etc?

edit

I'm trying to follow the starter guide on ROS Wiki by installin ros distro kinetic (I need this one because the projects that I'm working on need to work on Ubuntu Xenial). Here's my dockerfile:

FROM ubuntu:xenial

RUN apt-get update && apt-get install -y cmake build-essential lsb-core unzip

RUN DEBIAN_FRONTEND=noninteractive apt-get install -y cmake git build-essential libboost-all-dev libpcl-dev libproj-dev libvtk6-dev libusb-1.0-0.dev

RUN sh -c 'echo "deb http://packages.ros.org/ros/ubuntu $(lsb_release -sc) main" > /etc/apt/sources.list.d/ros-latest.list'\
    && apt-key adv --keyserver 'hkp://keyserver.ubuntu.com:80' --recv-key C1CF6E31E6BADE8868B172B4F42ED6FBAB17C654\
    && apt-get update && apt-get install -y python-rosdep \
    && rosdep init && rosdep update 

ENV LD_LIBRARY_PATH="/opt/ros/kinetic/lib/:${LD_LIBRARY_PATH}"
ENV PATH="/usr/local/lib/quanergy_client_ros/:${PATH}"
ENV ROS_ROOT="/opt/ros/kinetic/share/ros"
ENV ROS_PACKAGE_PATH="/opt/ros/kinetic/share"
ENV ROS_MASTER_URI="http://localhost:11311"
ENV ROS_PYTHON_VERSION=2
ENV ROS_VERSION=1
ENV ROS_DISTRO="kinetic"
ENV ROS_ETC_DIR="/opt/ros/kinetic/etc/ros"

The problem is that I don't get any of the tools mentioned in the tutorials like roscd, rostopic, roscore, rosrun, etc. I only have these:

rosdep                        rosdistro_build_cache         rosdistro_migrate_to_rep_141  rosdistro_reformat            
rosdep-source                 rosdistro_freeze_source       rosdistro_migrate_to_rep_143  rosversion

what am I doing wrong?
