Here's one solution:

const updateDockerImageName =
R.over(R.lensProp('groups'),
       R.map(R.over(R.lensProp('apps'),
                    R.map(R.when(R.propEq('id', '/1/B/i'),
                                 R.over(R.lensPath(['container', 'docker', 'image']),
                                        R.replace(/^NAME:VERSION1$/, 'NAME:VERSION2')))))));

This could be decomposed into smaller functions, of course. :)
