# amqp-ping's runtime: the tool runtime, carrying this module's compiled code. # # **Built from this module's own directory and nothing else.** The sdk and the tool runtime are not # copied out of neighbouring checkouts — they are in the base image, which is published like any # other artifact. That is what makes this buildable by the mesh from a repository and a path # (novox/hq ADR 0069) rather than only on a workstation that happens to have the siblings. # # Two bases, named rather than pinned: the image this is COMPILED in, and the image it RUNS in. # They are different images on purpose — the first carries a compiler and the second must not, or # every running container would carry one it never invokes. The mesh answers both with the copies it # holds, because a fingerprint written here would name one particular copy and no other mesh has it # (novox/hq issue 044). Declared in module.json's `build.on`; deliberately no defaults, so a build # nobody told stops here and says which module to build first. ARG BUILD_BASE ARG RUNTIME_BASE FROM ${BUILD_BASE} AS build # Compiled under /app/modules, so resolving `@novox/mesh-sdk` walks up to the base's own # node_modules — the module is compiled against exactly the sdk it will run against.
