This is the only way to be certain that you are choosing the appropriate version suffix.

You should always visit an image's DockerHub page before pinning to a specific version.

See container image updates to understand how to tell the difference between images that are used "as is" from DockerHub versus those that are built from local Dockerfiles. You use the Image ID to resolve the ambiguity. One will be tagged "latest" (the running version) while the other will be tagged "\" (the prior version). You will find two containers with the same name. The most common situation where you are likely to need the Image ID is after an image has been updated on DockerHub and pulled down to your Raspberry Pi. In general, you can use the repository name to remove an image but the Image ID is sometimes needed. When your Dockerfile changes, you need to rebuild like this: When Dockerfile changes ( local image only) ¶ You can also add nodes to Node-RED using Manage Palette.Node-RED also provides a good example of why your Dockerfile might change: if you decide to add or remove add-on nodes.

If a newer base image appears on DockerHub.

There are two separate update situations that you need to consider: The Dockerfile defines some (or possibly all) of your add-on nodes, such as those needed for InfluxDB or Tasmota. Node-RED is a good example of a container built from a Dockerfile.

The Dockerfile "runs" to build a local image.

A base image is downloaded from from DockerHub and then.

updating images built from Dockerfiles ¶Ĭontainers built using Dockerfiles have a two-step process: There is barely any downtime for affected containers. The up -d notices any newly-downloaded images, builds new containers, and swaps old-for-new. It does this without disrupting the running stack. With a few precautions, you can switch between git branches as much as you like without breaking anything.

"New New Menu" on the experimental branch.

This was inherited from gcgarner/IOTstack.

switching menus ¶Īt the time of writing, IOTstack supports three menus: You should come back and explore them once your stack is built and running. The old and new menus differ in the options they offer. The commands in this menu execute shell scripts in the root of the project. This is especially true if you select the SQLite node.īe patient (and ignore the huge number of warnings). Depending on the Node-RED nodes you select, building the image can also take a very long time. Some containers also need to be built locally. How long this takes will depend on how many containers you selected and the speed of your internet connection. The first time you run up the stack docker will download all the images from DockerHub.
