+may be incompatible with other elements of your software stack. Also

+may be incompatible with other elements of your software stack. Also

+<hr class="half-width"><p><strong><em>Nelson is a graduate student in
+microbiology.</em></strong> They have experience in running Unix shell
+commands and using libraries in R for the bioinformatics workflows they
+have developed. They are expanding their analysis to run on 3000 genomes
+in 200 samples and they have started to use the local cluster to run
+their workflows. The local research computing facilitator has advised
+them that Docker could be useful for running their workflows on the
+cluster. They’d like to make use of existing containers that other
+bioinformaticians have made so they want to learn how to use Docker.
+They would also be interested in creating their own Docker images for
+other lab members and collaborators to re-use their workflows.</p>
+<p><strong><em>Caitlin is a second year undergraduate in computer
+science examining Docker for the first time.</em></strong> She has heard
+about Docker but does not really know what it achieves or why it is
+useful. She is reasonably confident in using the Unix shell, having used
+it briefly in her first year modules. She is keen to find jump-off
+points to learn more about technical details and alternative
+technologies that are also popular, having heard that container
+technologies are widely used within industry.</p>
+<p><strong><em>Xu, a materials science researcher, wants to package her
+software for release with a paper to help ensure
+reproducibility.</em></strong> She has written some code that makes use
+of a series of Python libraries to undertake analysis of a compound. She
+wants to (or is required to) make her software available as part of the
+paper submission. She understands why Docker is important in helping to
+ensure reproducibility but not the process and low-level detail of
+preparing a container and archiving it to obtain a DOI for inclusion
+with the paper submission.</p>
+<p><strong><em>Bronwyn is a PhD student running Python/R scripts on her
+local laptop/workstation.</em></strong> She is having difficulty getting
+all the tools she needs to work because of conflicting dependencies and
+little experience with package managers. She is also keen to reduce the
+overhead of managing software so she can get on with her thesis
+research. She has heard that Docker might be able to help out but is not
+confident to start exploring this on her own and does not have access to
+any expertise in this within her local research group. She currently
+wants to know how to use preexisting Docker containers but may need to
+create her own containers in the future.</p>
+<p><strong><em>Virat is a grad student who is running an obscure
+bioinformatics tool (from a GitHub repo) that depends on a number of
+other tools that need to be pre-installed .</em></strong> He wants to be
+able to run on multiple resources and have his undergrad assistant use
+the same tools. Virat has command line experience and has struggled his
+way through complex installations but he has no formal CS background -
+he only knows to use containers because a departmental IT person
+suggested it. He is usually working from a Windows computer. He needs to
+understand how to create his own container, use it locally, and train
+his student to use it as well.</p>

+<hr class="half-width"><p>In addition to our individual learner profiles above, we also look at
+three more general groups who may want to learn about containers. This
+is intended to help you get a perspective of the different types of
+skills and expertise that learners engaging with this material may
+have:</p>
+<ul><li><p><strong>Researchers:</strong> For researchers, even those based
+in non-computational domains, software is an increasingly important
+element of their day-to-day work. Whether they are writing code or
+installing, configuring and/or running software to support their
+research, they will eventually need to deal with the complexities of
+running software on different platforms, handling complex software
+dependencies and potentially submitting their code and data to
+repositories to support the reproduction of research outputs by other
+researchers, or to meet the requirements of publishers or funders.
+Software container technologies are valuable to help researchers address
+these challenges.</p></li>
+<li><p><strong>RSEs:</strong> RSEs – Research Software Engineers –
+provide software development, training and technical guidance to support
+the development of reliable, maintainable, sustainable research
+software. They will generally have extensive technical skills but they
+may not have experience of working with or managing software containers.
+In addition to working with researchers to help build and package
+software, they are likely to be interested in how containers can help to
+support best practices for the development of research software and
+aspects such as software deployment.</p></li>
+<li><p><strong>Systems professionals:</strong> Systems professionals
+represent the more technical end of our spectrum of learners. They may
+be based within a central IT services environment within a research
+institution or within individual departments or research groups. Their
+work is likely to encompass supporting researchers with effective use of
+infrastructure and they are likely to need to know about managing and
+orchestrating multiple containers in more complex environments. For
+example, they may need to provide database servers, web application
+servers and other services that can be deployed in containerized
+environments to support more straightforward management, maintenance and
+upgradeability.</p></li>

+<p>Here we provide some example profiles of people who represent the
+target audience for this lesson. These example scenarios are designed to
+give you an idea of the different reasons people might want to learn
+Docker and the types of roles that they might hold.</p>
+<p>The profiles provided here and the individuals described are
+fictional but they represent the lesson developers’ experiences of
+teaching members of the research community about Docker and other
+container technologies over a period of several years. They also
+incorporate feedback from instructors involved in pilot runs of this
+course.</p>
+<p>Note that containers are applicable across a wide range of use cases
+within the research and High Performance Computing communities. These
+profiles are not intended to cover all areas but rather to offer some
+examples of the types of roles people learning this material might hold
+and their reasons for learning about containers.</p>
+<section><h2 class="section-heading" id="individual-learner-profiles">Individual learner profiles<a class="anchor" aria-label="anchor" href="#individual-learner-profiles"></a></h2>
+<hr class="half-width"><p><strong><em>Nelson is a graduate student in
+microbiology.</em></strong> They have experience in running Unix shell
+commands and using libraries in R for the bioinformatics workflows they
+have developed. They are expanding their analysis to run on 3000 genomes
+in 200 samples and they have started to use the local cluster to run
+their workflows. The local research computing facilitator has advised
+them that Docker could be useful for running their workflows on the
+cluster. They’d like to make use of existing containers that other
+bioinformaticians have made so they want to learn how to use Docker.
+They would also be interested in creating their own Docker images for
+other lab members and collaborators to re-use their workflows.</p>
+<p><strong><em>Caitlin is a second year undergraduate in computer
+science examining Docker for the first time.</em></strong> She has heard
+about Docker but does not really know what it achieves or why it is
+useful. She is reasonably confident in using the Unix shell, having used
+it briefly in her first year modules. She is keen to find jump-off
+points to learn more about technical details and alternative
+technologies that are also popular, having heard that container
+technologies are widely used within industry.</p>
+<p><strong><em>Xu, a materials science researcher, wants to package her
+software for release with a paper to help ensure
+reproducibility.</em></strong> She has written some code that makes use
+of a series of Python libraries to undertake analysis of a compound. She
+wants to (or is required to) make her software available as part of the
+paper submission. She understands why Docker is important in helping to
+ensure reproducibility but not the process and low-level detail of
+preparing a container and archiving it to obtain a DOI for inclusion
+with the paper submission.</p>
+<p><strong><em>Bronwyn is a PhD student running Python/R scripts on her
+local laptop/workstation.</em></strong> She is having difficulty getting
+all the tools she needs to work because of conflicting dependencies and
+little experience with package managers. She is also keen to reduce the
+overhead of managing software so she can get on with her thesis
+research. She has heard that Docker might be able to help out but is not
+confident to start exploring this on her own and does not have access to
+any expertise in this within her local research group. She currently
+wants to know how to use preexisting Docker containers but may need to
+create her own containers in the future.</p>
+<p><strong><em>Virat is a grad student who is running an obscure
+bioinformatics tool (from a GitHub repo) that depends on a number of
+other tools that need to be pre-installed .</em></strong> He wants to be
+able to run on multiple resources and have his undergrad assistant use
+the same tools. Virat has command line experience and has struggled his
+way through complex installations but he has no formal CS background -
+he only knows to use containers because a departmental IT person
+suggested it. He is usually working from a Windows computer. He needs to
+understand how to create his own container, use it locally, and train
+his student to use it as well.</p>
+</section><section><h2 class="section-heading" id="group-profiles">Group profiles<a class="anchor" aria-label="anchor" href="#group-profiles"></a></h2>
+<hr class="half-width"><p>In addition to our individual learner profiles above, we also look at
+three more general groups who may want to learn about containers. This
+is intended to help you get a perspective of the different types of
+skills and expertise that learners engaging with this material may
+have:</p>
+<ul><li><p><strong>Researchers:</strong> For researchers, even those based
+in non-computational domains, software is an increasingly important
+element of their day-to-day work. Whether they are writing code or
+installing, configuring and/or running software to support their
+research, they will eventually need to deal with the complexities of
+running software on different platforms, handling complex software
+dependencies and potentially submitting their code and data to
+repositories to support the reproduction of research outputs by other
+researchers, or to meet the requirements of publishers or funders.
+Software container technologies are valuable to help researchers address
+these challenges.</p></li>
+<li><p><strong>RSEs:</strong> RSEs – Research Software Engineers –
+provide software development, training and technical guidance to support
+the development of reliable, maintainable, sustainable research
+software. They will generally have extensive technical skills but they
+may not have experience of working with or managing software containers.
+In addition to working with researchers to help build and package
+software, they are likely to be interested in how containers can help to
+support best practices for the development of research software and
+aspects such as software deployment.</p></li>
+<li><p><strong>Systems professionals:</strong> Systems professionals
+represent the more technical end of our spectrum of learners. They may
+be based within a central IT services environment within a research
+institution or within individual departments or research groups. Their
+work is likely to encompass supporting researchers with effective use of
+infrastructure and they are likely to need to know about managing and
+orchestrating multiple containers in more complex environments. For
+example, they may need to provide database servers, web application
+servers and other services that can be deployed in containerized
+environments to support more straightforward management, maintenance and
+upgradeability.</p></li>

+software package and dependency versions within your
+<code>Dockerfile</code> rather than just specifying package names which
+will generally install the most up-to-date version of a package. This
+may be incompatible with other elements of your software stack. Also
+note that storing only a <code>Dockerfile</code> presents
+reproducibility challenges because required versions of packages may not
+be available indefinitely, potentially meaning that you’re unable to
