error cluster-needs

What it means#

needs lists the requirements a node must satisfy to take the role: label("key=value") (a node label), cpu(n), mem(size), disk(size) and gpu(n) (positive amounts known at build time).

Example#

cluster demo {
  role gpu { needs label("gpu") }   // <- cluster-needs
}

cluster-needs

How to fix#

Write the label as key=value and use a known resource: needs label("gpu=true"); needs mem(8gb).
