Environments organize configuration for different deployment contexts.

neb env list
neb env list --environment production

Create a new environment for your deployment topology.

neb env create staging
neb env configure production

Set environment variables with appropriate sensitivity levels. Variables are stored with policy-controlled visibility.

neb env set DATABASE_URL --environment production
neb env set API_KEY --environment production --sensitive
neb env set SECRET_KEY --environment production --sealed
neb env set BUILD_FLAG --environment build --availability build
neb env set FEATURE_FLAG --environment development --save

Once a variable is sealed, it cannot be read in plaintext. Sealed values require deployment-time injection through policy.

neb env seal API_SECRET --environment production

Export variables for shell integration or deployment tools. Sealed variables are not included.

neb env export --environment production > .env.production

Compare variables across environments to understand configuration drift.

neb env diff
