Snap notes

yq installs with with strict confinement in snap, this means it doesn't have direct access to root files. To read root files you can:

sudo cat /etc/myfile | yq -r - somecommand

And to write to a root file you can either use sponge:

sudo cat /etc/myfile | yq -r - somecommand | sudo sponge /etc/myfile

or write to a temporary file:

sudo cat /etc/myfile | yq -r - somecommand | sudo tee /etc/myfile.tmp
sudo mv /etc/myfile.tmp /etc/myfile
rm /etc/myfile.tmp

On Ubuntu 16.04 or higher from Debian package:

Docker

Oneshot use:

docker run --rm -v ${PWD}:/workdir mikefarah/yq yq [flags] <command> FILE...

Run commands interactively:

docker run --rm -it -v ${PWD}:/workdir mikefarah/yq sh

It can be useful to have a bash function to avoid typing the whole docker command:

yq() {
  docker run --rm -i -v ${PWD}:/workdir mikefarah/yq yq [email protected]
}

Parsing engine and YAML spec support

Under the hood, yq uses go-yaml v3 as the yaml parser, which supports yaml spec 1.2. In particular, note that in 1.2 the values 'yes'/'no' are no longer interpreted as booleans, but as strings.
