base image. This means that you can take the functions of one application delivered as an image and build new functions on top of that image. Thus, you need to understand how to maintain the dependencies upon the derived image as well as the new functionality. The assumption should be that you’re rarely starting an application from scratch, and those charged with container development are looking more and more at using OPC (other people’s code), which is much more productive. How- ever, it does bring up challenges with the lifecycle of the container, considering that you’re not tracking many dependencies. It’s a pretty clear problem that must be solved. If there is a step where develop- ers find and leverage prebuilt container images, you need to figure out where you’re Ѽѽɔѡɽݡɔ׊eɔѼ́ѡѼͥ)ѡɅѡ)eԁٕɅɥمєɕͥѽѼѽɔ䁽ѡ͔׊eɔ)ٕɅ́ݕ́ȁѕͥ́ѼѡQمх́ѡЁ)ɕхɥ䁽ѡݡȁѽ镐ٕͥѡ)͕́5ɕٕȰԁѽɔѡѽ镐Ѽѡͅ)ɥمєɕͥѽ)!ݕٕȰݡѡ́ɽѕ́ԁɽ́ѼѡՉѡЁ)܁Q́ѡЁձɕȁхȵ͕)ѥQԁݽeЁѡ́Ʌ́՜́Ѽѡɥ))Qݕȁ́Ѽ͔хȵ݅ɔɅѥЁѕ)]Ё́ͥѼЁɅѥѽ́Ѽхȁа)ѡɔɔхѥ̸ȁܰѡЁɅѥ́ѼݽɬݥѠȁɕ)ɅѥЁɽ٥ȁѼչх܁ѥѽ͕́)Ё͕Ѽхȵ͕ѥ̸ ЁѡЁ啅ȁ)ͼɕɕѼͥȁѥ=́ѽٕ́ȁ)ѕȁѽ) хȁQѥ)Qɔɔ䁅ɽ́Ѽѕѥх̸%ӊéхЁѼɕȰ)ѡ՝ѡЁѽѥхȁѕѥ́䰁ѕȁݡЁɽ)ԁٕɅ)]Ѡх̰ԁѕЁѽѥͥȁͥe׊e݅ЁѼ)ȁɕхѕЁ٥ɽ̰ݡɔԁոѡͅѕЁͥ)ѡͅѽѕѕѥѽ̸Q́́ѡЁѡѕѥ́Ёѡ)ѥս́ѕɅѥѽхѽ嵕Ёѽ%ѡ)݅䰁ѕѥݥѕɽѡЁٕȁ́ɕѼѕЁѼѡ)ѥЁ́ѼɽՍѥ)]ѠѡͥѡхȁɽѼѕѥх̰ѡѕѥѽ)ɔЁѡQ̰ѡ䁅ɔѽѥ䁍ɕ(؁Q!=AA1H10
