+Call me hint-on-tool. Some years ago--never mind how long precisely--having

+the rear of every funeral I meet; and especially whenever my hypos get
+such an upper hand of me, that it requires a strong moral principle to
+prevent me from deliberately stepping into the street, and methodically
+knocking people's hats off--then, I account it high time to get to sea
+as soon as I can. This is my substitute for pistol and ball. With a
+philosophical flourish Cato throws himself upon his sword; I quietly
+take to the ship. There is nothing surprising in this. If they but knew
+it, almost all men in their degree, some time or other, cherish very
+nearly the same feelings towards the ocean with me.

-Need to pull Docker image
-Can't run in container because it doesn't have access to Docker from inside -> how can we workaround?
-Turns out we also can't run in container because cwltool doesn't pathmap inside "Any" (this is a bug -> fix this)
-Try setting up a virtualenv -> annoying because you need C dependencies to build
-Virtualenv sets up shop in /tmp instead of the real directory
---relocatable ???
+List test cases:
 
+$ cwltool --print-targets main.cwl
 
-arvados/jobs doesn't have the docker client
-arvbox has docker client
 
-- Still need venv or something to run cwltool to manage all this.
-- Unless we run cwltool in docker as well.
+Run a specific test case:
 
-Can use cwl-docker.sh to run cwltool in docker
-
-- arvbox needs Docker.  This will *probably* work launched from container if base dir is under PWD
-- want to run arvados-cwl-runner.  this needs Docker to pull images.
-
-For a-c-r solutions are one of:
-
-1) Don't run in Docker, use virtualenv instead.
-2) Access to Docker from inside Docker to pull images.
-2a) Docker-in-Docker
-2b) Bind mount Docker socket
-2c) Communicate to Docker daemon over TCP
-3) Arvados feature to pull images

+Call me threestep-remote. Some years ago--never mind how long precisely--having
+little or no money in my purse, and nothing particular to interest me on
+shore, I thought I would sail about a little and see the watery part of
+the world. It is a way I have of driving off the spleen and regulating
+the circulation. Whenever I find myself growing grim about the mouth;
+whenever it is a damp, drizzly November in my soul; whenever I find
+myself involuntarily pausing before coffin warehouses, and bringing up
+the rear of every funeral I meet; and especially whenever my hypos get
+such an upper hand of me, that it requires a strong moral principle to
+prevent me from deliberately stepping into the street, and methodically
+knocking people's hats off--then, I account it high time to get to sea
+as soon as I can. This is my substitute for pistol and ball. With a
+philosophical flourish Cato throws himself upon his sword; I quietly
+take to the ship. There is nothing surprising in this. If they but knew
+it, almost all men in their degree, some time or other, cherish very
+nearly the same feelings towards the ocean with me.

+Call me scatter-gather-s1. Some years ago--never mind how long precisely--having

+the circulation. Whenever I find myself growing grim about the mouth;
+whenever it is a damp, drizzly November in my soul; whenever I find
+myself involuntarily pausing before coffin warehouses, and bringing up
+the rear of every funeral I meet; and especially whenever my hypos get
+such an upper hand of me, that it requires a strong moral principle to
+prevent me from deliberately stepping into the street, and methodically
+knocking people's hats off--then, I account it high time to get to sea
+as soon as I can. This is my substitute for pistol and ball. With a
+philosophical flourish Cato throws himself upon his sword; I quietly
+take to the ship. There is nothing surprising in this. If they but knew
+it, almost all men in their degree, some time or other, cherish very
+nearly the same feelings towards the ocean with me.

+Call me remote-case. Some years ago--never mind how long precisely--having

+shore, I thought I would sail about a little and see the watery part of
+the world. It is a way I have of driving off the spleen and regulating
+the circulation. Whenever I find myself growing grim about the mouth;
+whenever it is a damp, drizzly November in my soul; whenever I find
+myself involuntarily pausing before coffin warehouses, and bringing up
+the rear of every funeral I meet; and especially whenever my hypos get
+such an upper hand of me, that it requires a strong moral principle to
+prevent me from deliberately stepping into the street, and methodically
+knocking people's hats off--then, I account it high time to get to sea
+as soon as I can. This is my substitute for pistol and ball. With a
+philosophical flourish Cato throws himself upon his sword; I quietly
+take to the ship. There is nothing surprising in this. If they but knew
+it, almost all men in their degree, some time or other, cherish very
+nearly the same feelings towards the ocean with me.

+Call me twostep-home-to-remote. Some years ago--never mind how long precisely--having
+little or no money in my purse, and nothing particular to interest me on
+shore, I thought I would sail about a little and see the watery part of
+the world. It is a way I have of driving off the spleen and regulating
+the circulation. Whenever I find myself growing grim about the mouth;
+whenever it is a damp, drizzly November in my soul; whenever I find
+myself involuntarily pausing before coffin warehouses, and bringing up
+the rear of every funeral I meet; and especially whenever my hypos get
+such an upper hand of me, that it requires a strong moral principle to
+prevent me from deliberately stepping into the street, and methodically
+knocking people's hats off--then, I account it high time to get to sea
+as soon as I can. This is my substitute for pistol and ball. With a
+philosophical flourish Cato throws himself upon his sword; I quietly
+take to the ship. There is nothing surprising in this. If they but knew
+it, almost all men in their degree, some time or other, cherish very
+nearly the same feelings towards the ocean with me.

+Call me Ishmael. Some years ago--never mind how long precisely--having
+little or no money in my purse, and nothing particular to interest me on
+shore, I thought I would sail about a little and see the watery part of
+the world. It is a way I have of driving off the spleen and regulating
+the circulation. Whenever I find myself growing grim about the mouth;
+whenever it is a damp, drizzly November in my soul; whenever I find
+myself involuntarily pausing before coffin warehouses, and bringing up
+the rear of every funeral I meet; and especially whenever my hypos get
+such an upper hand of me, that it requires a strong moral principle to
+prevent me from deliberately stepping into the street, and methodically
+knocking people's hats off--then, I account it high time to get to sea
+as soon as I can. This is my substitute for pistol and ball. With a
+philosophical flourish Cato throws himself upon his sword; I quietly
+take to the ship. There is nothing surprising in this. If they but knew
+it, almost all men in their degree, some time or other, cherish very
+nearly the same feelings towards the ocean with me.

commit 46d3a59fdedee791b3fc5b19ad64c7417235cf2c
Author: Peter Amstutz <pamstutz at veritasgenetics.com>
Date:   Thu Oct 25 10:36:47 2018 -0400

    14198: Use PDH for container_image instead of docker repo+tag
    
    Needed to support federated container requests.
    
    This reverts 6ea807b2caf6c934f170b2e4d89c23c4a08ca69c
    
    Based on the commit comment, that change was made to accomodate the
    Docker v1 to v2 image format migration (to enable the API server to
    select the image with the correct format).  However, the API server
    subsequently gained the ability to detect if it needed to substitute a
    PDH with a migrated image PDH in commit
    a72205728f94f5261b657766e01f5767dc15d4b5 so now we want restore the
    original behavior of locally resolving the image PDH and using that in
    the container request.
