Article Robert Cemper · Sep 4 4m read IRIS in Docker for beginners The article was motivated by the 2025 September Article Bounty***************************************************************The principle of Docker is just convincing to me. Get a sandbox where you play and try whatever you want/need to do Once done. You drop it without leaving traces in your working environment This was the technical base for me to run about 700 reviews in OEX with almost no side effects (except those caused by myself). #Docker #InterSystems IRIS 7 2 3 32
