Variables in devcontainer.json?

[jalanh11640]

Is there anyway to specify a variable in devcontainer.json? I'm thinking something like this..

"variables": {
"HOST": "myHostName"
},
{ // devcontainer.json starts here
...
"runArgs": [
"-h", "${variables:HOST}"
],
"postCreateCommand": "vscodePostCreate.sh ${variables:HOST}"
}

Thanks,
Jeff

Hi 👋

Are you familiar with containerEnv and remoteEnv?
Look at https://containers.dev/implementors/json_schema/ for more details/

Thanks for the reply. I wasn't familiar with those. However, looking at the documentation, neither of those look like they'll support what I'm trying to do. I have several places in my devcontainer.json where I've used the same value. I was hoping to find a way to specify the value once, and use it multiple places within the devcontainer.json file.
