How to use nrf-docker in Bitbucket pipeline

Question

I want to create automatic build using CI in bitbucket pipeline. 
 I would like to use image NordicPlayground / nrf-docker to compile the project. I saw the article Build NCS application firmware images using Docker - Getting Started - nRF Connect SDK guides - Nordic DevZone (nordicsemi.com) . 
 The usage of this image looks like: 
 docker run --name ncs --rm -v ${PWD}:/workdir/ncs/fw-nrfconnect-nrf ncs /bin/bash -c 'cd ncs/fw-nrfconnect-nrf/applications/asset_tracker; west build -p always -b nrf9160_pca20035ns' 
 But I would like to first run the image, and inside run the west build command. 
 
 There is my example runner configuration. 
 pipelines:
 default:
 - step:
 name: 'Build'
 image: nordicplayground/nrfconnect-sdk:v2.5-branch
 runs-on:
 - self.hosted
 - linux
 script:
 - echo "Building start"
 - west --version 
 And on output i got: 
 
 + west --version
bash: west: command not found 
 
 How to solve this. Eventually how to modify the docker image to obtain what i want.

I found the solution. I need to make the file launch_tool.sh: #!/bin/bash

# Checking whether an argument has been passed
if [ "$#" -eq 0 ]; then
 echo "You must provide at least one command to execute."
 exit 1
fi

# Passing the command to nrfutil toolchain-manager launch
nrfutil toolchain-manager launch -- /bin/bash -c "$*"
 
 And the step definition - step: &build_for_nrf52840dk_faster
 name: 'Build for nrf52840dk board'
 image: nordicplayground/nrfconnect-sdk:v2.7-branch
 runs-on:
 - linux
 script:
 - HW_VERSION="0.0.0"
 - source /workdir/zephyr/zephyr-env.sh # make visible west build
 - chmod +x launch_tool.sh # make launch_tool.sh executable
 - ./launch_tool.sh west --version # check west version
 - ./launch_tool.sh west build
 --pristine=always
 --board nrf52840dk/nrf52840
 --build-dir ${PWD}/build
 --
 -DBOARD_ROOT=${PWD}
 -DCONF_FILE=${PWD}/prj.conf
 - mv build/zephyr/zephyr.hex nrf52840dk_v${HW_VERSION}.hex
