The `docker` CLI currently doesn't handle situations where the current context
(as defined in `~/.docker/config.json`) is invalid or doesn't exist. As loading
(and checking) the context happens during initialization of the CLI, this
prevents `docker context` commands from being used, which makes it complicated
to fix the situation. For example, running `docker context use <correct context>`
would fail, which makes it not possible to update the `~/.docker/config.json`,
unless doing so manually.
For example, given the following `~/.docker/config.json`:
```json
{
"currentContext": "nosuchcontext"
}
```
All of the commands below fail:
```bash
docker context inspect rootless
Current context "nosuchcontext" is not found on the file system, please check your config file at /Users/thajeztah/.docker/config.json
docker context rm --force rootless
Current context "nosuchcontext" is not found on the file system, please check your config file at /Users/thajeztah/.docker/config.json
docker context use default
Current context "nosuchcontext" is not found on the file system, please check your config file at /Users/thajeztah/.docker/config.json
```
While these things should be fixed, this patch updates the script to switch
the context using the `--context` flag; this flag is taken into account when
initializing the CLI, so that having an invalid context configured won't
block `docker context` commands from being executed. Given that all `context`
commands are local operations, "any" context can be used (it doesn't need to
make a connection with the daemon).
With this patch, those commands can now be run (and won't fail for the wrong
reason);
```bash
docker --context=default context inspect -f "{{.Name}}" rootless
rootless
docker --context=default context inspect -f "{{.Name}}" rootless-doesnt-exist
context "rootless-doesnt-exist" does not exist
```
One other issue may also cause things to fail during uninstall; trying to remove
a context that doesn't exist will fail (even with the `-f` / `--force` option
set);
```bash
docker --context=default context rm blablabla
Error: context "blablabla": not found
```
While this is "ok" in most circumstances, it also means that (potentially) the
current context is not reset to "default", so this patch adds an explicit
`docker context use`, as well as unsetting the `DOCKER_HOST` and `DOCKER_CONTEXT`
environment variables.

The Moby Project
Moby is an open-source project created by Docker to enable and accelerate software containerization.
It provides a "Lego set" of toolkit components, the framework for assembling them into custom container-based systems, and a place for all container enthusiasts and professionals to experiment and exchange ideas. Components include container build tools, a container registry, orchestration tools, a runtime and more, and these can be used as building blocks in conjunction with other tools and projects.
Principles
Moby is an open project guided by strong principles, aiming to be modular, flexible and without too strong an opinion on user experience. It is open to the community to help set its direction.
- Modular: the project includes lots of components that have well-defined functions and APIs that work together.
- Batteries included but swappable: Moby includes enough components to build fully featured container system, but its modular architecture ensures that most of the components can be swapped by different implementations.
- Usable security: Moby provides secure defaults without compromising usability.
- Developer focused: The APIs are intended to be functional and useful to build powerful tools. They are not necessarily intended as end user tools but as components aimed at developers. Documentation and UX is aimed at developers not end users.
Audience
The Moby Project is intended for engineers, integrators and enthusiasts looking to modify, hack, fix, experiment, invent and build systems based on containers. It is not for people looking for a commercially supported system, but for people who want to work and learn with open source code.
Relationship with Docker
The components and tools in the Moby Project are initially the open source components that Docker and the community have built for the Docker Project. New projects can be added if they fit with the community goals. Docker is committed to using Moby as the upstream for the Docker Product. However, other projects are also encouraged to use Moby as an upstream, and to reuse the components in diverse ways, and all these uses will be treated in the same way. External maintainers and contributors are welcomed.
The Moby project is not intended as a location for support or feature requests for Docker products, but as a place for contributors to work on open source code, fix bugs, and make the code more useful. The releases are supported by the maintainers, community and users, on a best efforts basis only, and are not intended for customers who want enterprise or commercial support; Docker EE is the appropriate product for these use cases.
